I just installed Fontbase and opened it and started activating some Google fonts. Then I remembered to sign in for the additional stuff. I had been scrolling through the Google fonts, hadn’t added any of my personal collection. But after I signed in, all that disappeared. I can’t see my 21 active fonts, can’t see the Google fonts. This app is useless - how do I fix it? Also bummed to discover Fontbase only recognizes 2 font formats! I will have to keep using my old font manager to support all my older work 
Hello @janmart49, thank you for the post, welcome to the forum 
Would you be able to add a screenshot of how your FontBase window looked like you’ve logged in and everything disappeared?
Thank you again,
