@sgambo , I finally managed to resolve it when Glide customer rep suggested to sign out of Airtable & Glide and only then try to delete and re-authorise the connection again. Then it finally worked.
So I think it’s not that the Airtable integration doesn’t work anymore and need to be fixed (first CS reply was a bit confusing) but more about some specific issue which should be resolved with the right troubleshooting.
Find below the response that helped me:
For troubleshooting purposes, could you please log out from both Glide and Airtable, then log back in and try re-authenticating again?
