After upgrading to Pro, Zoom keeps logging me out of my Macbook and iPhone app

I finally caved in and upgraded to the Paid Pro version yesterday. After I did it,  it logged me out of all of the devices, but it did not let me log back on. It lets me log back on to my Macbook, but not on my iPhone app, and even on the Macbook, it keeps signing me out after some time and keeps it from staying logged on as I used to be able to keep on.

I do not have SSO or anything like that, just a personal account. I have looked at all settings, restarted the machine, and re-installed the desktop and iPhone apps, but no luck.

I did not change any settings when upgrading associated with automatic sign-out or only allowing one device to log in to the account, so I am baffled as to why it is doing this.

I would appreciate any advice you can give me on how to fix this. Thank you.
