Resolve the “Content Unavailable” error in TrialPad when importing from Box by updating, refreshing, or reinstalling the Box app on your iPad.
When importing documents from Box (or another cloud provider), you may see the alert:
Content Unavailable
The folder contents could not be displayed because of an unknown error.
This error comes from iPadOS and Box, not TrialPad. The Box File Provider extension is responsible for showing your folder contents. If it can’t connect, TrialPad cannot load your files.
Troubleshooting Steps to Try:
1. Check your connection.
Confirm your iPad is on a stable Wi-Fi or cellular connection. Unstable or slow connections may cause this error.
2. Update apps and iPadOS.
Install the latest versions of iPadOS, the Cloud Service app (Box, etc), and TrialPad.
3. Refresh Box in Files.
Go to the Files app > ⋯ (ellipsis) > Edit Sidebar > turn Box off > tap Done. Force-quit Files, then repeat but turn Box back on.
4. Sign out and back in.
In the Box app, go to Home > Profile icon > Settings > Log Out. Then log back in.
5. Reinstall Box.
On your iPad, go to Settings > General > iPad Storage > Box. Choose Offload App or Delete App. Restart the iPad, reinstall Box from the App Store, and sign back in.
(This step resolves the issue for most users.)
6. Check folder size and path.
Very large folders (10,000+ items) or long folder names/paths may fail to load. Try smaller folders or reorganize files.
7. Check restrictions.
Disable any Box passcode or MDM restrictions that may block access.
If the Issue Persists
Contact Box Support. Provide them with:
-
A screenshot of the error
-
Box app version and iPadOS version (Settings > General > About)
-
Whether the same folder opens in the Box app itself
-
Approximate number of items in the folder
As a temporary workaround, you can copy files to On My iPad in the Files app and then import them into TrialPad.
