unable to open PhotoShop

Hello all;

Thank you very much for taking the time to give your thoughts regarding my problem.

For months now I have been unable to open PhotoShop on iPad or iPhone.

Works fine on Mac laptop.

What I get immediately upon opening the app on both devices is a blue spinning circle, no error message.

Prior to this there were a variety of error messages including:

"Unable to authenticate. We're unable to connect to Creative Cloud"

or 

I would log in and it would bounce back to the login page.

here are the details...

iPad Pro, 4th Generation, iOS 26.0.1, PhotoShop 6.6.2

iPhone 16 Pro Max iOS 26.0.1, Photoshop 6.6.2

Some of what I have tried to fix the issue:

restarting app

uninstall/reinstall app

checking version for update

signing out of all other Adobe apps

checked my Internet connection

check clock setting

signing out of my Adobe account and signing back in

dumping cache

hard reboot of device(s)

logging out of Creative Cloud and logging in

etc., etc., etc.: all the basics I could think of and glean from researching the issue

In addition:

this is not the first time this has happened basically out of the blue where the apps work fine then suddenly can no longer be opened...

A year ago I spent much time speaking with Adobe CS

(*sigh*) 

I followed ALL their recommendations, sending video, etc.

to no avail

UNTIL:

at some point (with an update to the app?) it would become usable again and I would be able to log in.

So,

I'm wondering what solutions I might find here to be able to use something I am paying a monthly subscription for?

Thank you again for taking the time to assist.
