Merge Academy – Progress Saving Issue (Update)

It doesn't matter which browser or device I use - on my phone, on my laptop, in Safari, in Edge, in Chrome - it doesn't save, period.  Not the main game, not the treasure trove, not the sticker packs, not collecting freebies from the generator - none of it works.  It was all fine until some point this morning, since I was able to collect some of the generators, but before I was able to collect all of them.
