We are working on the bug found by @dkbit98 to improve error message, so that we can see what actually happened (I suspect it was related to app permissions).
I am glad I was the first one to publicly find a bug without actually doing a code review

Known bugs are likely UI only and have no security implications.
Maybe, but result is that app is currently not unusable for me.
Security implications is secondary if you don't have any usability.
