Banding after denoise since latest update to Lightroom cloud edition on apple silicone.

I believe that I've figured it out.   I'm not a landscapes guy,  so I was just in a hurry to get them done.  I used one of the recommended presets,  and made minor adjustments to it.  Which included adding denoise.

Once denoise was turned off,  it all went back to normal,  with no banding.  I then reset the photo,  and edited it by hand.  I was unable to replicate manually.  I believe the Ai Recommended presets might have a setting in them causes this.  Not all presets,  just some.

   I came here because people on Reddit are complaining of the same issue using Classic.

I’ve tried this in Lightroom Classic on an M2 Max and don’t see any banding. I used a photograph that has plenty of empty sky (negative space) and even when I crank Dehaze to +100 there aren’t any problems.

Can you post an example photo?

Also, you mention Lightroom “cloud edition” but posted into the Lightroom Classic community. I don’t expact that to matter in this instance, but just in case...
