"Device not supported" message for Adobe Account Access app on iPhone 11

Does anyone know how to troubleshoot this issue? I downloaded the Adobe Account Access app to sign in to Adobe Creative Cloud on an Android device and it works perfectly. I downloaded it on to an iPhone 11 running IOS 14.2 from the App Store (https://apps.apple.com/us/app/adobe-account-access/id1514571935) and after installing it on the device, I immediately received an error message upon opening it that said "Device not supported" and was given only two options: a blue button that said "Learn More" and when clicked took me to this page https://helpx.adobe.com/manage-account/using/passwordless-sign-in-adobe.html and another button that said "Close App." I've read everything on the link from the "Learn More" button, including the FAQ at the bottom about this issue. The iPhone meets all the requirements of the FAQ but I'm still getting the error message. Any suggestions?
