Update the App and Restart Your Device

Outdated applications can cause integration bugs with iOS system files and third-party cloud storage services.

Compatibility issues between Adobe Fill and Sign and newer iOS versions can often lead to cloud storage files failing to display. Keeping the application updated to the latest release ensures integration patches are applied.

1
Check for updates

Open the App Store on your iOS device, search for 'Adobe Fill & Sign', and tap the 'Update' button if a newer version is available.

2
Restart iOS

Hold down the power button (and volume button on newer models) to turn off your iPhone or iPad, then turn it back on to clear the system cache.

3
Test file access

Reopen the Adobe Fill and Sign app, navigate to the file browser, and attempt to access your Google Drive folders again.

Quick Tip: Regularly restarting your device can resolve temporary glitches in how iOS handles third-party cloud storage indexing.
