I am having a similar but weird issue.
I cannot logout and not reset my password. Thought something was wrong so was testing my login setup and not have an issue. Just using the lemm.me web interface.
Going to agree that the sound mixing sucks. It is much more enjoyable to watch a tv or movie when you can properly hear the dialog. I ended up watching subtitles so much I can’t stand to be without them.
No finding the !support so posting there :)
