When I try to add a new host pool VIA the portal I get an error message that states " ErrorLoadingExtensionAndDefinition" as the error reason. This happens from all browsers. I have cleared my cookies and have used private windows. This is also happening on my work computer along with my mobile devices. The only time i am able to access this page is when i am connected to my works VPN, however this is not my work environment. It is my personal tenant. I have no conditional access policies in place and I am access azure with a Global Admin who is also an owner on the subscription. I have uploaded a screen shot of the error message for reference
