Adobe DC in app sign-in page is blank for all users in Microsoft AD remote desktop

IT Pro here,

     I figured sence none of these solutions worked for me (Mac OS) I would post the soloution I found.

1) Delete all Certificates, Passwords, Etc. within keychain access. - anything mentioning Adobe, purge it.

2) Un-install and re-install adobe using the adobe uninstaller application and the download link.

3) Success.

After the re-install it should promt you to cache a new sso login username and PW (This is why we clear keychain access).  Go thru the sign in process as you normally would, and with any luck you should be up and running!

We only get this blank page after login if the user has not completed their SSPR (self service password reset) information in Azure (after the Azure message ""Your organization needs more information to keep your account secure").
As soon as the user has completed his SSPR information in another way (e.g. "https://mysignins.microsoft.com"), this error/white page does not occur anymore.
However, we do not have another/direct solution yet, so that the SSPR page is displayed correctly.
