Hello, which plan should I upgrade to, in order to use premium tier 1?
Welcome to the Make community!
Are you on the Free plan, and have you tried upgrading to the Core or Pro plans yet?
From what I know, only Tier 3 apps requires Enterprise plans.
Hope this helps! Let me know if there are any further questions or issues.
