On the topic of Workfront being whack lately...

Proof for us is completely shut down with a popup about Classic expiring that persists when opening a Proof. No workaround, can't do anything with a proof, clicking OK does nothing. And we are not on Classic. On hold for quite a while with Support, at some point I have to get on with my evening. Sheesh.

It was fixed within about 30 minutes. Still a blunder but a quickly corrected one.

I was just about to open a support ticket for this issue, but looks like it's been fixed somehow

We are having the same issue with Workfront Proof - we've already moved to the New Experience and we're getting a popup warning about the upcoming change and we can't get it to clear.
