I used to use RiF back in the day when it was still a buggy mess. I don’t even remember when I moved to the native app. I don’t agree with Reddit’s policy update (why I’m here) but I thought the default app was fine for normal browsing. I never had issues with the video player or anything else.
I use Samsung Galaxy devices if that’s relevant.
I used to but then they added ads in the comments and I had had enough me undie ads so I installed infinity and haven’t looked back
