Of cource: Maybe @svengabr can push that subject to the developers again, because if deleting CWA data proves to reliably bring back CWA to work, without deleting collected RPIs/own TEKs, then this method should be immediately made public to support a big crowd of users who frequently run into the problem of app crashes!

For the moment, I can't give a certain answer here, but if you describe, where you found the contacts with the timestamp, we'd have some more certanity...

CAUSE: 3 Something went wrong. Updated it just now. The log upload service is the counterpart of the log upload in the app. But one point of criticism is still left: I am a complete unsuspecting layman in app-building, but it is more than hard for me to understand why a workaround is necessary for not too less people just to make CWA working.

This issue will therefore be closed. Regarding the comment by @svengabr, my issue might be related in the sense that it's caused by aggressive background termination (until the crashes started, background update worked though; I had to reset the apps multiple times already because of #642).
