I've built an app in App Maker and deployed it, but the user I thought I had given permission to is getting this notification "Sorry, you don't have access to this application."
In the app, I added a role to the data source and added the user to the role from the deployment. I also added the role to each page's security. I verified that App Maker is turned on for all of our users. I've ensured that the user has access to the Google Sheet data tables (both what I imported into the App for preview and the data I exported from the deployment). I've even added the user as a Cloud Sql Viewer in our Cloud SQL instance (don't know if that was necessary). This is my first app and I feel like I'm flying blind. I'm obviously missing something but can't figure out what. Any help is much appreciated!
