Revision history is incredibly slow
For large files (not in size but the amount of objects in the hierarchy), clicking on a revision history is incredibly slow. I have a real download speed of 350 Mbps yet it takes a few minutes to load each revision history.
Another problem is that there is no loading progress bar. Because of this, it is not clear when the revision is finished loading. The effect of this is that you click on one revision, not what you are looking for, click on the next one, not the one you are looking for, click on the next one, etc, without any idea that it actually was not finished loading and somewhere you clicked on the revision you were looking for but due to a "finished loading" notification, you don't know what revision you are actually looking at.
This is a major UI issue and should be fixed.
I just tested a Rive file that has over 300 assets and am experiencing the same thing. I'll ping the engineers and let them know we need better UX. I'll also see if there's anything we can do to speed up the process. I'll keep you posted.
