Preview does not correspond to the presentation


I’m kinda new to Prezi and two days ago I worked on my first presentation, when I opened my profile the preview corresponded to what I did but when I went for modifying it the presentation missed many of the modifies that I did two days ago. It’s strange because the preview is up to date but when I open it it suddenly changes. Do you know how to solve this issue? Presentation link:


Hello, @Fausto_Verza.
I have checked the presentation and I can confirm that the current version is the fullest one. Could it be possible that when the changes were made your connection was not stable? The edits, if they were made, did not reach our servers.
Please note that the thumbnail does not represent the presentation currently as it might have been generated while you were editing the content which was later not saved properly.
I apologize for any inconvenience.
