From a certain point in time, I have had a problem with an opening in editing mode for every presentation (even a new template or blank). A presentation window opens, but after that circle in the middle of the window spins forever and nothing else happens. I tried to reinstall the app, clean remains, etc. but to no avail. The only way is to use Prezi in the Chrome window, but it is less convenient than using the app. Did anyone have the same issue?
