Hi,
I had the same problem last time (related pic). This time I thought I'd posted from my computer, but I only have the delete option on my phone (so I guess I had a misperception).
So I don't know if:
>I took too long to edit the post (In that case, why do I see the option?)
>If my dynamic IP affects anything (Although I don't think so, because I haven't deleted my cookies. And generally when that happens, it doesn't even give me the OP option).
>No idea.
Anyway, I get a "Bad request" message (somewhat generic). It doesn't happen when I delete other threads or posts; I think I'm missing something.
Also:
I suspect it has to do with editing times or some problem recognizing me as OP. But hey, I have the option.
Maybe this will help in the future.
