Power Apps access errors expose hidden permission layers

A newly updated Power Apps troubleshooting guide maps the separate access layers behind an “Access Denied” error: the shared app, its connections, the data source, flow access, and any record-level permissions. Its practical warning is that an app can open successfully while a user still cannot load, submit, or update the data it relies on.
For a SharePoint-backed internal app, the demo can look healthy because the maker has access to everything. The failure only appears when a colleague reaches a list, item, connection, or flow path they were never granted, which makes the app feel randomly broken. The useful response is not to give everyone Full Control. Treat the error as an access-chain test: identify the exact operation that fails, then confirm the minimum permission needed at each layer before changing the app.
Analysis
Test one real-user account through the app’s read, create, update, approval-flow, and error paths. Record the required SharePoint, connection, and flow permissions beside the release checklist.
