Platform: iPad Pro, latest OS
Lightroom version: 9.5
Issue: when I apply a monochrome profile (specifically any of the cobalt images Monochrom M10 profiles, but I suspect any similar) the profile applies, but as of this app release any attempt to adjust the RAW (exposure, highlights, etc) reverts the image to color, and automatically sets the profile to Adobe Color. Prior to this update, they functioned normally as a base profile, and still work fine on desktop (MacOS, latest Lightroom CC version)
specific steps:
1. Take any color raw you have
2. Apply profile; the M10 profiles in question are XMP profiles with an RGB LUT that's applied after all image controls (per Cobalt; I checked with them first). Note the image goes monochrome as expected.
3. Make any adjustment in the develop panel, such as exposure, shadows, contrast, etc
result: image resets to color, profile UI briefly freezes, automatically sets Adobe Color after few seconds. Profile can be reapplied, but issue repeats.
On desktop, this does not reproduce; everything is functioning normally, and these profiles also functioned normally prior to this app version.

Screen cap/gif of what it looks like in action. Sequence is "select RAW, apply profile, adjust contrast". Opening/closing the profile menu without making changes shows the reset to Adobe Color.

Update: I've contacted the profile creators, and also tested against all other (web, Mac desktop) LR clients I have access to; the issue appears to be isolated to the iPad client, and only to the latest version; the profile creators (Cobalt Images) also feel this is a bug in the Lightroom iPad client. All other versions don't exhibit the same incorrect behavior as regards reversion of the image to color.

The Lightroom iOS team would like to investigate this further. Are you able to share the offending profile with us?

Thanks. I will see if that is all the engineer needs.

Oh, one note is that as a prereq, they require a base pack of DCPs for your particular camera; there's one in particular that's marked as a base/starting point for the emulation XMPs, and I'm happy to share that as well if needed. (It won't let me upload it.)

The engineers have requested the DCP. Can you upload it to a shared service (Dropbox or similar) and then DM me the link?

One more item, can you supply the image original from your test GIF?

Hey, followup; just tested in 9.5.1 iPad and the issue still appears to reproduce. (Obviously I have no idea if that's expected, but I'm a fan of providing as much info as I can just in case.)
Were you guys able to reproduce this with the sample images/profiles I sent?

I'm seeing the same issue. It's been here for months. Very frustrating - any updates from the Adobe team?
