We had to upgrade DNS and ssl certificates this week and it’s causing some issues with 2.0 and Android beta where review items are no longer being saved. As you pointed out, legacy.skritter.com does not have this issue (it’s accessing v1 of our API rather than v2). We’re aware of the issue and are trying to find a solution for it as quickly as possible. We’ll be sure to reply to the relevant threads once the solution has been deployed.
Sorry for the troubles and stay tuned for the fix!
