@CarissaM, I am using the desktop download. However, yesterday, Rebecca at TT helped me over the phone. I did not believe her when she asked me to try a simple solution: Reboot my fiber optics internet modem/router - turn off for 2 minutes and turn on. Everyone with a MacBook Pro running Catalina (and maybe other OS versions, too) + fiber optics internet to the home: follow the on/off instructions - don't cheat on the timer, stay with 2 minutes or more - it worked for me.
I went from top down in my trouble shooting because I knew more about programming, which was pointless. I do not know enough about hardware and data transmission, which is, apparently, the area of expertise that is needed. I still don't understand why it worked, but it did. Maybe something similar to clearing out the cache in a computer? Rebecca deserves a raise and a reward for dealing with me.
