Yes I did, maybe you can find the screenshot in this thread because I believe I've shared it here as well as in duelbits ANN thread since I won it at duelbits before the pandemic if I remember it correctly. You are right that it is getting harder now to hit max win on Pragmatic games, but I think my luck is already over on this provider so I hit no more max win for so long time but of course it is also because I played less than before. Basically Fruit Party can be said as the game which give more frequent max win, in one casino there are at least 2-3 players who get max win every day based on the lucky win information. I hit max win in this game as well once long time ago at rollbit.
A screenshot is not really super solid proof of reality though. Specially these days of AI.
I think something like a big win transferred to an address with a signed message would be the gold standard of proof.
Anyone can alter an image.
