Playing on Ps4, was collecting gwent cards now for 10 hours (including checking lists multiple times) trophy is not popping. Really upset and angry...
Considering the reports of no trophies popping at this point, it seems highly likely that this is the root cause of the Gwent card malfunction. Although one piece of evidence against this is that the in-game quest doesn't complete either. Perhaps CDProjectRed can post an authoritative list of cards to collect? That'd be quite helpful to confirm whether we're experiencing a bug. I've seen many posters complain about not getting this trophy while simultaneously admitting they lack some cards, considering them dupes or "not counted". Who says?
I had a straight-forward road to collecting the cards and finished the random ones after the 1.07 patch. I didn't get the quest or trophy. My last card was the Wyvern (interesting how many collected this last). I used the gwentcards.com checklist to confirm my collection. But even that one is anecdotal.
Let's get those bug reports to CDPR quickly and include save files when you can. That will decrease their time to resolve.

Does at least the quest itself finish for you?
Yeah this is my second play through as well but PS4, and I used the same website to check my cards. I am not going to finish the quest till they fix it. I can see me completing it, but whatever patch comes out does not give the trophy/quest completion retroactively and then having to do a third playthrough. Granted that wouldn't be horrible since its an awesome game, just a lot of work.
