@TikTak123 I have not been able to reproduce this one, but I believe it has been fixed in the latest snapshot. If you're able to reproduce at all, please try it out!

dimsuz commented 3 years ago

Hi @EricKuck! I'm curious, do you plan to cut the release soon(-ish) with all the bugfixes you (and others) have fixed?

EricKuck commented 3 years ago

@dimsuz Yes, a new release will be cut within a week. I'd like to hear if the issue is fixed for @TikTak123 first if possible, but I'm not sure if he's actually able to repro or if these are just random crashlytics logs.

TikTak123 commented 3 years ago

@EricKuck This is random crashlitycs logs. Today we will release a new version on Google Play. I'll give you feedback in a few days.

TikTak123 commented 3 years ago

The new version runs for 3 days on prod. So far, I haven't seen a single crash regarding this.
