I'm pretty sure I've asked this before, but a search didn't turn up my post or anything exactly on point.
It seems as if I'm having to log in quite often, even with Remember Me checked and on the same device. The timing is intermittent with no pattern I can detect so far. Does the site 'reset' or something like that? It's not a huge issue, but it IS a bit annoying for something that, on its surface, shouldn't seem to be happening.
