Add ins in Microsoft 365 are not working
I noticed an add in was missing when I logged into Word. I tried readding it and I get an error message that says error loading add ins. I am unable to upload add in to any Microsoft application.

Please check, it may due to tenant-level policy blocking add-ins, a corrupted local add-in cache/manifest, or a known service-side delivery issue that Microsoft is actively mitigating.
