If you use Row Owners, the app cannot download rows not owned by the logged-in user. We currently have a Preview As visibility issue in the Glide Builder which will be fixed. But again in the app running outside the builder only rows that are owned by the logged in user are downloaded.
Mark referenced the link to the older other thread “Row Level Security” that was posted before Glide implemented the Row Owner feature as a reference to the old method which was not a secure way to protect this data.
