Account Recovery, Recovery Phone

I want to input my cell phone number into, and associate it with my Adobe account.

Logged int at accounts.adobe.com, I go to Overview, Security & Privacy, Account Recovery, Manage, Recovery Phone, Add, and input my cell phone number, and click "Text Me".  I am supposed to get a code texted to me, which I then type in to validate my phone number and associate it with my Adobe account.  Every single time I try to do it, it takes 10-15 minutes for Adobe to text me the code, so that by the time I get the text with the code, Adobe has signed me out of my account, forcing me to sign back in, and then go through the entire process again, and this keeps repeating in an endless loop. There does not seem to be a way to get back to the screen where I can input the code that Adobe texted me.

Since Adobe takes so long to text me the code, and since Adobe logs me out before the code arrives, and since Adobe will not let me back to the screen to input the code that finally texted me, I am forced to re-input my phone number, and wait for a new code.

This process continues ad infinitum, presumably until I give up or die.

Any suggestions would be appreciated.
