Hi ​@ECFernandes, 

Welcome to Box Community, and we’re glad to assist! 

Here are some suggestions for your issue with Box on iPad Pro 11 running iOS 18.6 where some sub-folders/files show “no internet connection” despite having internet:

1. Network Issues: Mobile devices often face network interruptions causing issues like files/folders not loading properly. Try connecting on a different network and see if that would work.

2. Refresh & Reinstall: For files/folders not showing up or loading inconsistently, try refreshing the app and uninstalling/reinstalling it to clear any caching problems. 

3. Check Account & Permissions: Ensure you are logged in with the correct account and have proper permissions to access those folders. 

4. Scale Limitations: If folders contain thousands of files or very deep folder structures, you may hit scale limitations that cause some content not to load. 

5. Offline Marking Conflicts: If you marked some content for offline use, ensure there is enough storage space and no conflicts with automatic cache settings. 

6. App Version: Make sure you are running the latest version of the Box app as updates often fix bugs related to connectivity and file access.

Hope it works, and please let us know how it goes.
