Android app started working after reinstalling but web still same

I have resolved the issue by restoring server backup. Cause unknown, but it had something to do with reverting & then upgrading the snap. I have no access to the broken version anymore so Im closing this

Glad to hear you that you could fix the problem. However, I'm not happy, that a single erroneous file can break the whole app. Therefore, I've implemented an improved error handling for such a situation, see #593.
