P: Mobile: Switches camera profiles unexpectedly

I have spent quite some time creating custom camera profiles using Adobe dng profile editor and a colour chart to give me accurate color with no twists etc
So to find that when I sync photos from lightroom desktop I have to use an included profile is a right pain
But worse is that when on the road and I import raw photos to the iPad I cannot change from Adobe standard
Please is there any way around this
I have shelled out for this iPad to do this work and it's proving that both the device and software isn't yet capable

Interesting! Did you try a recent import with the latest software versions?

Maybe my workaround can be of help for you?

The problem I see (described above) - difference in behavior of CR2 and DNG files - does not seem  to be affected by the age of metadata. 

I think I am on to something here.

It seems with the most current versions of LR (CC 2015.8) and LR mobile (2.6.0) it has mostly to do with the age of metadata.

If I freshly import a file (Olympus E-M1 in my case for instance) then the camera profile sticks, even if I do edits in LR mobile.
If I go into a file that was imported in LR a while ago and I change the camera profile back and forth, LR mobile will no longer revert it to Adobe Standard.

This is where my guess comes from that refreshened metadata (by changing the profile back and forth) will lock in the profile and LR mobile won't change it.

I haven't tried if other changes in LR's the develop module will accomplish the same, but for now I will just bulk switch the camera profile for all oder files, hoping that this will lock the profile for LR mobile.

Apparently, LR Mobile (including Lightroom web) does not know about custom camera profiles that are applied to Canon CR2 raw files.   The mobile versions are always rendered in Adobe Standard.   This of course makes mobile editing tof CR2 files useless wrt color.   On the other hand, when you convert such a CR2 file to DNG and sync that version, the mobile versions are rendered correctly with the custom camera profile. 

Such different behavior for CR2 and DNG surely is a bug.
