I’m on a tablet, using Safari, if that information is useful.
I have a suspicion that every time I receive an alert (new posts to a thread I’m following, being @‘d, etc.), the ‘post/edit’ button becomes nonfunctional. Every time I have to go through the rigmarole I described above, the alert button lights up after I hit refresh. Not so sure about the edit function, but I think it’s the same issue: if the system has an alert for me while I’m posting or editing (which I don’t see as the page hasn’t refreshed yet), then the post or edit is blocked. The edit, unfortunately, is permanently blocked, as if the time limit had expired.
Do all of you have some alerts enabled? Do the unaffected people have alerts disabled?
edit: when attempting edits that don’t go through, the ‘save’ button on the upper R side is always grayed out.
