Creating a new App Registration in Azure, app disappears

For a specific Azure tenant, when I create a new app registration, it just disappears and is nowhere to be found.

It gets assigned an application id:

I am also able to create a key for it:

and view properties for it:

But when I go to refresh the list of apps (or go somewhere else to pick it for identity access control) - it is just nowhere to be found. Like this:

If I go to Azure Active Directory Overview, it says I have 4 applications (which fits the number of times I have create a new app registration) - but if I click it - nothing found.

Note:

• The account I am using is a global admin
• I have also tried doing this with the owner account of this tenant, same result
• This works in all other tenants
• I have tried logging out and back in
• I have waited (days), does not change anything

What is happening?
