When I go to the iFlash Deck Library, it has a button that says: "Browse Available Card Decks." But when I click on it I get nothing -- just a blank page. At the top of the page, it does say "Loading Decks...." I thought that perhaps it just took a long time to load, so on three separate occasions I tried hitting the link and then walking away from the computer for an hour or so. Nothing.
I don't see anyone else in this group talking about this problem. Apparently there was some difficulty in 2019 with the Apple OS Update to Catalina. That thread says the problem was resolved in twitter -- which is of no earthly use to me (or anyone else.) I did follow iFlash on Twitter, but I'd appreciate a response here, if possible.
