Lightroom Mobile stuck on “Importing – 1 pending” when opening any photo from Device

Lightroom Mobile for iOS v11.5.1 is stuck on “Importing – 1 pending” whenever I try to open/import any photo from the Device tab.

This started recently. Previously, I could open photos from my iPhone and edit them normally without any delay.

The issue happens with every photo I try. The import remains pending and the photo does not open for editing.

I have already tried:
- Restarting the iPhone
- Signing out and back into my Adobe account
- Offloading and reinstalling Lightroom
- Testing different photos
- Checking Lightroom Web for sync issues
- Confirming I have plenty of Adobe Cloud storage available
- Testing my internet connection (around 86 Mbps)

The problem still persists.

Device: iPhone
Lightroom version: 11.5.1 (7C3095/251)

Please advise if this is a known issue or if there is a way to reset the stuck import/sync queue.
