I am currently trying to create an automated marketing email in Shopify. I have admin access and everything, but as soon as I click on "create email campaign" it redirects me to a page that says "Oauth error invalid_request: This app is requesting to be reinstalled and your account does not have permission to grant the requested access. You may be able to resolve this issue by reinstalling the app as the account owner."
I have tried clearing cookies and using three different types of browsers and it did the same thing. Has anyone run across this issues/does anyone have a solution?
You may want to verify the account owner has given you the correct permissions. Having admin is a pretty vague reference because in Shopify there isn't an admin per se. There are staff accounts where the store owner can set permissions individually to a staff account.
