Unable to log in with Lightroom Mobile app (v11.6.21) on iOS 27.0.1

I am attempting to log in to my Adobe Lightroom account using the Lightroom Mobile application on an iPhone with iOS 27.0.1.

I launch the app, I see the 4 login choices and choose the Continue with email option.

I am given a page (auth.services.adobe.com) which prompts me to log in with my email address.  I enter my Adobe account email address and the page fails at this point.  I am unable to select the Continue button nor am I able to edit the email address.  

I can refresh the page but cannot progress through the continue button.

I know my account is active as I can log in to lightroom.adobe.com on my laptop’s browser and I can log in using my Lightroom Classic application on my Mac.

Edit to add:

I have reinstalled the application, refreshed network settings, force closed the app, and none of these steps have remediated the issue.
