What did you do to the forum?
One can’t paste text here anymore, which is quite an important feature.
Sometimes, buttons in the post-writing window become unresponsive and I have to leave the topic and then go back to the draft for them to work again.
The cursor can get misplaced and hover where it shouldn’t in the post you’re writing, making editing harder.
And there’s probably more…
I definitely didn’t have these issues more than a year ago. I’m using Safari on my iPhone/Mac just like before.
