So today I decided to bite the bullet and get into Logos 9 silver. I already the desktop app. after my purchase I opened the app again and it had a synchronization issue. killed it, reopened, still had the issue. restarted my computer and reset my password (it made me log back in after restart). it logged me in fine. I watched the progress status bar as it was downloading. all was fine. I was logged in, browsing around the app when suddenly the app crashed. I get the dreaded "logos quit unexpectedly..." message. I reopen the app and now its forever stuck on the "preparing your library" screen and the app won't open.
MacBook Pro running Catalina.
