Camera Profiles disappeared!

I updated today to Lightroom CC Classic.

And I'm really regretting it.

Most of my recent work was treated with a camera profile I bought from RNI, its a lot flatter profile So i can export to photoshop and color grade the photos like i want to there, fix skin, compose, etc... then export back into lightroom for library management, do a final develop and post online from there.

Well, my most recent photos all look very different now! because the new Lightroom doesn't use camera profiles! it does says my image is using RNI 4.03 profile, but it say its missing, and im not given the option to select it again or any other camera profile other than the embedded, or basic ones like color, monochrome, and come useless stuff, like Creative, Vintage, etc...

Some of you will say that profiles are still available, but have been moved, well, picture profiles yes, they have been moved, and are still accesible, including my RNI ones, but those ara XMP files, the camera profiles, DCP files are gone! and are not usable! RNI most use a camera profile from them to be able to use their picture profiles!

So, are we ever gonna get that back? the ability to choose our Camera profiles?

BTW, Every time i open lightroom now, it tires to convert picture profiles to XMP, it succeeds, but again every time does it again!

So, should I keep using the old Photoshop Lightroom CC 2015.14??? How long will that be available and supported? Or should i just change my workflow and use Capture One or just Photoshop?
