Agree! This is super frustrating for people that receive or are notified about lots of @mentions within comments on proofs - if the proof version has moved on, it's impossible to locate the @mention. The notification should also include a preview of the @mention in the comment.

Sometimes there will be a comment left on an earlier version proof and they'll tag a team member. That annotation notification only takes them to the action card, not the specific annotation - you're left to dig through the annotations in various proofs to find the one you were tagged in.

Yes, I tried out the Proofing feature but immediately wasn't into the UI. Controls/icons were too small, adding annotations didn't seem very intuitive. Not as easy to use as other solutions we've tried and will stick with for now.
