Hi,
I had this issue (you mentioned my post in your message).
It was fixed and I didn’t have to rebuild my apps.
I was using Airtable API to connect to Airtable and wanted to switch to OAuth connection to anticipate Airtable API deprecation.
So I added the OAuth connection to all the apps that connected to Airtable.
At some point I had 2 connections to Airtable in my apps : the API connection and the OAuth connection.
For some reason, I could not remove the API connection by myself.
Glide support did it for me. And now I connect to Airtable using OAuth and it seems to be fine so far.
But your case might be different because I didn’t see the error message you are showing. So maybe, you should try again to add the OAuth connection.
