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 love your honesty. I expect for many people it’s more about losing what they’re comfortable with. For others there are legitimate functionalities that perhaps don’t exist yet in the native app - a former mod will need to chime in, as I’m not sure about specifics.
