PL-900 Demonstrate the capabilities of Power Apps Practice Question
A user built a canvas app that uses a SharePoint list. When they add the app to a Teams channel, some users cannot see the data. The app works fine when opened directly from Power Apps. What is the most likely cause?
Answer choices
Why each option matters
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
The users do not have permissions to the underlying SharePoint list
The most likely cause is that users do not have permissions to the underlying SharePoint list. When the app is accessed via Teams, the app runs in the context of the user, and SharePoint permissions are enforced. Even though the app works when opened directly from Power Apps (if the user has permissions), adding it to a Teams channel may expose users who lack access to the list. Option A is incorrect because licenses are per user and not specific to Teams; if users have Power Apps licenses, they can use the app. Option B is incorrect because the app works outside Teams, so the connector is not deprecated. Option D is incorrect because the SharePoint connector does not require a Premium license in Teams.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
The users do not have Power Apps licenses assigned
Why it's wrong here
Licensing would block app access entirely, not selectively hide SharePoint rows for some channel members. The app opens fine directly, so the licence exists. This option would fit a scenario where users cannot launch any Power Apps at all.
- ✗
The app uses a deprecated connector
Why it's wrong here
A deprecated connector would fail for all users, including the maker opening the app directly, so it cannot explain data visible in Power Apps but not in Teams. Deprecated connectors are tempting because they do cause failures, but the correct cause is missing SharePoint list permissions for the Teams users.
- ✓
The users do not have permissions to the underlying SharePoint list
Why this is correct
Canvas apps connected to SharePoint inherit the list's item-level permissions; users lacking SharePoint list access see no data even though the app itself is shared. This explains why direct Power Apps access works but Teams access fails.
- ✗
The SharePoint connector requires a Premium license in Teams
Why it's wrong here
SharePoint is a standard connector included with seeded Power Apps for Microsoft 365, so no Premium licence is triggered by Teams embedding. Premium licensing applies to connectors such as SQL Server or custom connectors, which is where this reasoning would hold.
