The HSK Level 2 should have 772 words, at least according to the wikipedia page. In the level 4 it indeed looks like one word is missing. The was one duplicate in the level 4, but that has now been removed.
By the way, this has nothing to do with the beta release… 
There is one version of the HSK word list here: https://raw.githubusercontent.com/elkmovie/hsk30/main/wordlist.txt
At least in this list the word 批 is twice (once as a verb and once as a measure word). This might explain why one word is missing.
@Apomixis please move this stuff into the HSK thread and maybe tag Olle as well so we can take a look.
I flagged these as off-topic thinking you’d get the alert but now I just see two flags in my admin inbox LOL
3.6.0 Beta (300528)
Happy studying!
I just noticed that rejuvenating a deck brings up the “Goal achieved” text (if there is enough words to be rejuvenated). The number of learned words doesn’t change and if I look at the daily goal, I’ve only learned one word today (so the goal has not been really achieved, which is of course correct).
Have you managed to look at the vanished cursor when editing definitions for iPhones? Sometimes it’s there, sometimes it isn’t.
We have an open issue for it, but it is not in the scope of the Progress release. It will be fixed up in the future though.
@Therebackagain in the meantime, if your tap-hold the space bar on your phone keyboard it’ll pull up a way to quickly move your cursor anywhere, which should make it much easier to find the cursor :0
3.6.2 (300538) beta rolling out soon!
Here are the juicy details.
Happy studying!
Nice fixes, thanks.
I’m still looking forward to being able to browse lists and have a place-marker so that when I leave the list I have inspected, I go back to where I was while browsing, instead of having to start all over at the beginning.
This makes browsing lists so tedious that I just don’t do it anymore, which is a shame, as there’s plenty to explore.
The search function is terrific and fast - yet only if you know what you are searching for, so it doesn’t help browsing.
Also, while browsing, it takes so long to load the icons for each list that the scrolling freezes from time to time.
Would be nice if one could make one’s way down a series of lists without having to wait repeatedly for the unfreeze and the icons to fill in.
Hopeful you will fix this soon!
Improving the smart-loading system on decks is on the list, but we have a few other changes we’d like to deploy with it that’ll make the whole process and experience better than ever!
Will be addressed and improved!
3.6.2 (300539) should now be out on Android and iOS. We found an audio plugin failure on Android and had to get it fixed up for y’all.
We’re going to be moving fast with this build so be sure to let us know if there are any major bugs you’re spotting otherwise we’ll get them in the next update!
Just a heads up that once we move to 3.7.0 builds (slotted for early September) I’ll be closing this megathread and starting a new one.
I don’t know if this is a Beta issue:
Just recently I have come across a number of words where the reading is double-sounded. I’m not sure why this is necessary, if it is intentional; in fact, it is rather annoying.
Is there new audio that deliberately sounds out the word twice? If so, why?
This doesn’t sound deliberate, but if you can remember a few of the words that were played twice I can check them out. Is this happening during a review, test, or learning? Are you noticing it on any specific card type (eg. definition, reading, tone, writing)?
I am getting the same thing on some, but not all words. Doing the list 800 Prolific Characters in Learn mode and have had the following words all said twice in succession:
菜
粉
问
导
Using an iPad and Skritter 3.6.2
Are you tapping through the learning screens quite quickly? We repeated the audio each time a new card comes up so it could be a build-up of multiple taps playing audio. I just tried with some of these characters and couldn’t re-create the doubled audio.
Screen capture would be helpful so we can dig in deeper. Thanks, y’all!
Me? Learning quickly? Surely you jest! 
No, in all seriousness, I don’t think that is the issue. But just to check I did start another session just now. The only think different this time is I had enabled “rawest squigs” and I am still getting the “echo” or “stutter” effect. Just now it was on the word 痛 。 I was not doing any double tapping or advancing cards particularly quickly.
It seems to be happening on all the new words I am adding, and there are too many to list.
If I add words I’ve learned previously (a long time ago) it doesn’t seem to happen, but I can’t be completely sure about that.
It happens both during review, and during learn mode.
Not sure how a screen grab would help? This is an audio problem.
Also, it has nothing to do with speed, or with rawest squigs, at least in my experience.
After a while I found it less irritating, assuming it was deliberate repetition for our benefit! 
Also: can’t just be a beta problem. My partner doesn’t have beta and this is happening to him too.
I should add, there is another odd problem I haven’t encountered before, with a single phrase, and only with the traditional not the simplified version.
不怕一萬只怕萬一
The app accepts the handwriting for the first four characters, but refuses all strokes for the last four. Just nothing happens.
It is possible to tap through the last four characters to continue to the next card.
