Hello,
Thanks for reaching out to us. I have seen the similar case and this is the workaround we were using at that time(pictures are from internet):
Step 1: login to your azure portal
Step 2: find Subscriptions in left side menu bar and click.
step 3: Click on Access Control IAM and then click on Add.enter image description here
Step 4: In Add Permission window, select contributor for role. In select input box, type the app name you created in Azure AD (Created in Azure Active Directory)and select it. In my case I created Azure Resource Management.enter image description here
Step 5:After you have given successful permission, click on Refresh in your subscription window and you will see your app showing in the list. See below example. enter image description here
Hope this helps.
Regards,
Yutong
