Really nothing in that thread is helpful for this update crash issue. It's got nothing to do with image sizes or whatever - at least from what I've seen in my testing to narrow down the problem. I've tested a 1 page folio with nothing but a single word of text and it still crashes the app upon updating. The problem purely involves new folios created after the recent updates. When I update any of my older folios, they never crash.
Would sure love an update *pun intended* from Bob B on this issue.
