Sharing from gallery to messages in android kiosk shows "app isn’t allowed by device owner"Solved

Hi @skylar-a,
Since you are seeing that error even after temporarily disabling kiosk mode, it points directly to your restriction policies rather than your kiosk app list.

If messaging is disabled in your restrictions, Android will block the action entirely at the device owner level. To resolve this, you just need to adjust the advanced restrictions:

1. Open the policy applied to your Android devices.
2. Go to Restrictions > Advanced.
3. Scroll down to the Allow Account Settings section.
4. Enable the SMS setting and also enable the settings under it: Receive messages and Send messages.
5. Keep the required system communication packages you already added under Android > Kiosk Lockdown > Background Apps.
6. Save the policy and wait for it to refresh on the device.

Once those settings are applied, the native Messages app can send and receive normally. The background packages you added are safe to keep in the kiosk policy because they help Android handle the inter-app communication and media transfer.

Please let me know if this resolves the messaging error or if you have any other questions.

Best regards,

Enabling Send messages and Receive messages fixed it. After the policy refreshed, my contacts loaded normally in the Messages app, and I was able to share an image straight from the Gallery without the access denied message.

Glad to hear that resolved the issue and the devices are sharing media correctly now.
