I’ve found the fix for my issue I was re-authenticating two bases on separate projects. When re-authenticating, after I hit “Grant Base”, I selected only one base instead of “All current and future projects” in Airtable. That causing only able to authenticate one project (from one Airtable base) at a time.
(I was also following these steps - Urgent Issue: Glide <> Airtable Data Syncing Not Working (Error 1035) - #5 by jonlutz79)
