Noise reduction doesn’t apply when exporting

[Pops718]

Hi! 
I get a noisy image after export, although every noise reduction slider yet color noise are applied and the image looks crystal clear.  
I've tried out several export settings, color spaces too, but it didn't solve my problem. 
I put a comparison bellow. 

IOS, Lightroom mobile, v. 5.3.1 53B120, Premium. 

p.s.: I put noise reduction sliders all the way up to make this comparison more clear.

Just raised exactly the same problem. Applied the same edits in the app and on the desktop and see exactly the same results as you above. 

Have you had any response to your post?

Hi,

Please try the latest 5.4 release out and let us know if it solves the problem.

Thanks,
Ignacio

The bug still exists in the latest version. 

this is destroying my workflow and is having a serious impact on the quality I can deliver to clients.

Same here, since months. Its so nerve- wrackling. I just work with my ipad and the noise reduction function is horrible...

The silence on this from Adobe is shocking. I would recommend looking at Affinty and moving your post processing work to that if this isn't fixed soon.

Please confirm which version you are on, this should be fixed in 5.4.2.

thanks,
Ignacio

Default Noise Reduction value, no masking. 

I'm using 5.4.2 25D6E5 on both an iPad Pro 2020 and IPhone XR. Screen shots from iPhone as I don't have my iPads with me right now. 

below are some further examples of the bug along with screenshots of the noise and sharpening values of the image. These haven't been altered from the default when importing a new image. Also, the image was shot at ISO 320 so I appreciate there is some noise inherent in the image to start with.

I'm using version 8.5 on Android and the problem still persists... 

Any updates on this issue from Adobe?
