Hi Rekha,
can you send us a test account to mobile@moodle.com so we can check it? Also, please tell us the exact device you're using, some errors only happen in certain devices.
If you want the 3.1.1 version you can just go back to the commits on June 14, but I don't think that will fix the problem.
Kind regards,
Dani
