Add support for Modern Authentication
If you are blocking Claims Authentication in your Microsoft 365 Tenant, you cannot add SharePoint Sites in to Adobe, no login prompting occurs.
Reproduction steps:
1. In SharePoint admin center > Policies > Access control > Apps that don't use modern authentication, set to 'Block'
2. Try to add a SharePoint Site to Adobe
Environment: Windows 10
Expected result: Successfully add SharePoint Site to Adobe
Observed result: No login prompting or errors occur, dialog simply re-opens and does not add the SharePoint Site
It should be noted other PDF applications such as Foxit and Bluebeam Revu both support Modern Authentication currently, so unfortunately this may mean we have to move away from the Adobe Suite to other software suites for security reasons in the near future.

This is a critical and overlooked component that Adobe needs to address. Microsoft has nearly dropped all support for basic auth as it is an insecure method of authentication. I'm honestly surprised Microsoft allows for re-enablement for third-party apps. It is only a matter of time until they remove this option.
All that said, re-enabling basic auth in the Sharepoint admin center is a workaround and is not ideal from an infosec perspective.

We have found a solution.
You will not believe it:
Install Foxit Reader and add Sharepoint Online as a file location in Foxit. After Foxit has been successfully connected to Sharepoint Online, it is also possible to connect Adobe Reader to Sharepoint Online.Good work Foxit!

Getting Modern Auth as soon as possible is very important for us. Without Modern Auth, we have to replace Adobe with another PDF solution on all our clients.
