Prezi reverted a presentation to an older version

Hi Prezi Classic users,

I’m having trouble with a prezi I designed for a class I teach: I took a prezi from 2017 and updated it with current examples. I then used the updated version in class. So far so good.

However, this morning the prezi reverted back to its 2017 iteration, and I seem to have lost all the updates I added.

Any help would be appreciated!

Yes, and thank you kindly for your help:

Hello again Vanda,

Not to worry: I appreciate the help. Likewise, all content loss is major if I cannot reproduce it myself.

The last time the Prezi was what I wanted it to be was on Friday Sept. 7th at 11:30 am, MST.

All cheer!
