You can download previous revisions if you’re working with a team project (.rpteam). However, normal projects (.rp) don’t have the old versions available for download.
Is the project you’re looking at a normal project or team project? Team projects will have a pink icon in Axure Cloud.
I’m looking at normal project(.rp).
I thought the normal project had the roll-back feature as well. But I’m not sure about it.
And I found Axure Cloud web UI changed recent days which made think some features lost.
So it turns out to be my false memory.
Thank you for replying and have a nice day~
