Photos Not Syncing from Lightroom (Windows) to Cloud, iPad, or iPhone

I’m facing a sync issue with Lightroom (cloud version) on Windows. Certain photos that are visible in Lightroom on my Windows PC are not appearing in Lightroom on my iPad, iPhone, or even on Lightroom Web.

Here’s what I’ve tried so far:

• Confirmed I’m using the cloud version of Lightroom (not Classic).
• The Lightroom interface shows “Synced and Backed Up”, but affected photos do not appear on mobile or web.
• I tried adding these photos to new albums, reimporting them, and even exporting and reimporting into new albums — but they still don’t sync to the cloud.
• I also tried signing out and back in, clearing cache on mobile, and testing with new files — nothing works.
• File Info is not available for these photos, so I can’t check their sync status individually.
• I have local storage enabled under Preferences > Local Storage.

It seems Lightroom is storing these photos locally and not syncing them to the cloud despite reporting full sync. I suspect a sync database issue or a stuck background sync process.

Could you please help me force a resync or repair the Lightroom sync catalog so all photos upload to the cloud and show across devices?
