I have a SP Library in M365 which I am receiving the following error when I try to edit the document properties in Power Apps. The requested operation is invalid. Server Response: (lib name) failed: The query cannot be completed because the number of lookup columns it contains exceeds the lookup column threshold.
This library has old content types that I want to remove which I feel are causing the excess in the threshold limit. If I remove the fields in PowerApps, it still does not get rid of the error. I've removed the content types in the library & template, but they still exist in PowerApps. Is there any way to remove these old connections?
