Keep having to sign in.

All of a sudden I am having to sign in repeatedly to use Adobe apps.

Earlier to day when I opened Illustrator I got a pop-up saying Illustrator needed to shut down because I wasn;t signed in.

It said this was likely because I had either recently run the app on another device or I had changed my password. Neither of which was true.

I restarted it and it asked for my password which I entered and then was able to work.

Now about an hour later I opened Acrobat and was again asked to sign in.  I did and it said that acrobat was now licensed to my account.

What's going on?

Thanks,

Paul
