Hello. I posted this last year, but is still happening, and quite frustrating.
Whenever I move from edit mode to preview mode, I get the dialog box that it is exporting, but it continually reloads the page in a loop, never stopping to allow me to view the page. If I’m quick enough, I can scroll down to view the area I am trying to preview, but it soon starts the loop all over again, staring the page back at the top. I then need to time the re-loading just right to either hit cancel on the dialog box or the edit button. Based on advice from other threads, I opened a new project and previewed a page and it does the same thing.
