Yes. I don’t remember which Public Beta of 13 started the drain, but it was fixed until 13.1 when it returned. So yes, PB 13.1 and watchOS 5.3.1.
I can see why you wouldn't want to go to WatchOS 6 since it's nearly impossible to downgrade. But I see no reason not to at this point. I've been on it since June and it's worked fine.
Yes!!! Sharesheet is working properly again!
