So I have just upgraded to NLP. My workflow is that I would import negatives from my scanner to my laptop directly into lightroom classic. Then it would sync with my lightroom CC and mobile. I have just started DSLR scanning with my Canon R6mkii and in terms of using it on Classic it works flawlessly. But when I open up the pictures on lightroom cc or mobile, all the previews are extremely blue, and not a switch to auto warmth blue, like the preview is choosing the adobe default color profiles. It is not until I actually click into a singular photo and try to edit it do I see the photo in the correct profile. To sum it up, previews in grid form default to adobe profiles and not NLP profiles.
This is discussed elsewhere on the forum:
SOLVED: Synced images not displaying correctly on LR CC Mobile and Shared Libraries
tl;dr - Lightroom Mobile and Lightroom Desktop (non-classic) need to have access to the Negative Lab Pro raw camera profile (.dcp file) for the camera model in order for the RAW to display correctly.
