I use light room mobile and new images i take i can not transfer from my desk top Mac to my iPad also the denoise function when editing no longer works

Hi ​@dr4sail, Thanks for reaching out, and welcome to the Lightroom Community Forum! Let’s tackle these issues and clarify what’s going on.

Denoise not working: This is a known issue where AI edits as Denoise applied on one device can get stuck in a sync loop when viewed on another device. Our engineering team has identified the root cause, and a fix is currently being tested. It's targeted for an upcoming Lightroom update.

In the meantime, as a workaround, you can try applying Denoise only on the device where you plan to do your final editing.

Images not transferring from Mac to iPad: 

Please try these steps:

1. Check the cloud/sync icon in Lightroom Desktop (top-right) and make sure sync isn't paused or showing an error.
2. Verify both your Mac and iPad apps are updated to the latest version.
3. Check that your Creative Cloud storage isn't full (you can check at account.adobe.com).
4. Try signing out and back into your Adobe account on both devices.

If the photos that won't sync are ones you've applied Denoise to, the sync issue above may be causing the transfer to stall.

Let us know if those steps help with the sync issue, and we'll follow up once the Denoise fix ships. I hope this helps! ^CH
