[simonroesch]

Can you please provide a screenshot of the error when you come back to the app?

[tingsu]

Hi @simonroesch , I may not be able to provide the screenshot anymore. The reason is that I already updated my Google Play services. As a result, the notification of asking me to update the Google Play Services will not appear anymore. I cannot reproduce this issue unless I degrade my Google Play Services on my phone. Before this, I indeed encountered this reported issue.

From the crash stack, I guess the issue may reside in the org.dpppt.android.sdk when handling fragments.

[simonroesch]

I tried to reproduce this on a phone with Android 9 and degraded Google PlayServices, but I am not able to reproduce it. Also with having the developer option "Don't keep activities".

I will close this issue, please reopen if this can be reproduced with version 1.0.4-pilot or later.
