I have an app that I've uploaded to the App Catalog. When I go to a site collection and request that app I get the message "Your tenant administrator has to approve this app" and I request the approval.
Now when I navigate to the App Requests list in the App Catalog and click the request, I don't get the Approve/Reject screen but only the edit screen for the approval request.
I have tried to change the status of the request to Approved but that doesn't work. When I go back to the Site Collection and go to the Apps you've requested I can see Approved but when I click the application it says "Invalid SharePoint App ID"
I'm doing this with a user that is a SharePoint Admin and Site Collection Admin on the App Catalog Site Collection.
I've used this same app in a lot of different tenants without any problems.
Step 1 - App Request List in the App Catalog
Step 2 - The screen I get after I click the App Request in the App Catalog
Step 2.a - The screen I should get when I click the App Request in the App Catalog
Step 3 - What I see in "Apps you've requested"
Step 4 - After I click App Details in the "Apps you've requested" view
After a long search I thought I struck gold when I saw a similar post here but the answer in that post does not work for me.
