While it was editing my last prezi always it was offline and I trusted in that one was guarding me locally and then when it was returning to have connection that was raised only. The problem is that when I see the prezi in my dashboard, the miniature corresponds to the finished prezi, but when I enter to the presentation or to the edition, the complete prezi is not. I need urgent help!!!
As for being offline, please check this forum topic with our suggestions:
Please also share the link to your presentation so that I can check.
Thank you for the link. Could you please also send a screenshot of the differences you see between the editor and the thumbnail?
