Would you like to work on the issue?

I don't have the qualification to work on this issue

Hi, this bug should have been fixed in v2.13.1. Could you register for beta testing and let us know if it fixes the problem for you? Otherwise, the new version should be available to everyone by the end of the week (if everything goes well).

@misaochan

I installed the Beta but the problem still occurs.
From the crash log I've send:

Edit: damn...sorry I just remembered that you probably got a mail for every deleted msg...sorry :(

This seems to be a different one from the one mentioned in the original issue log, @fnordson So just to confirm, you are able to login in successfully but as soon as you get logged in, the app crashes?

@ashishkumar0207

Edit:

Just before the app disappears and the crash report pop-up comes up, I can see a "login successful text".
Here is the Video:

@misaochan Why has this been closed?
Is it supposed to be fixed (it isn't on my phone)?
Fixed in the next version?

[misaochan]

The associated PR has been merged, so the issue is auto-closed. It will be released in the next hotfix, which should be soon.
