[Android] "Syncing of adjustments is paused" is shown permanently — edits never sync automatically (Force Sync required)

Environment: Google Pixel 9 Pro Fold, Android 17, Lightroom Mobile 11.6.12, Premium subscriber, ~20 GB of free cloud storage

Steps to reproduce:

1. Edit any synced photo.

2. The cloud status shows "Syncing of adjustments is paused" (調整変更の同期は一時停止されています).

3. No matter how long I wait, the edits never appear in Lightroom Web. They are uploaded only when I manually tap "Force Sync."

Expected behavior: Edits should sync automatically in real time, as they did before.

Notes:

- Automatic sync used to work normally; it stopped working at some point.

- Happens on both Wi-Fi and cellular connections.

- Because of this issue, when the app force-closes during editing or my edits are reset by another bug (see my separate report about the Delete menu resetting all adjustments), the edits exist only in the local session — they are not saved as cloud Auto Versions either — so they are lost unrecoverably. If automatic sync worked, intermediate states would be kept as Auto Versions and could be restored.

Already tried (no improvement):

- Cleared the app cache (~4 GB)

- Reinstalled the app

- Signed out and back in

- Resumed sync; confirmed "Use cellular data" is ON

- Set Android app battery usage to "Unrestricted"

- Background data ON, Data Saver OFF

- No "Sync Issues" items in Lightroom Web

- Cloud storage is not full (20 GB free)
