No change. I tried Chrome on my tablet and I'm on IE right now on my laptop.
I did notice on my last few recent posts, there was an "edit" button. However the next time I came back to it, there was no edit button. The "quote" button is everywhere, so that's not an issue.
Very odd. I've never had this problem before until just recently. I always edit posts and I've done so on multiple devices on multiple platforms and on multiple connections. All of a sudden, I can't edit my posts anywhere (except my most recent post for a limited time.)
