This is on 2.0 build 40… 2.0 build 35 is working fine on my iPad

I updated the ipad to build 40 and its not working either… It appears i can not sign in properly because there is some error

The rateLimits issue is probably due to a missing or malformed push notification token.

No idea about that app_version issue, can you try reinstalling the app?
