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 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.
The native app is decent, if you haven't tried any of the other third-party apps.
I joined Reddit back during the Alien Blue days and transitioned over to Apollo when it launched. Using the native app felt like I stumbled onto a porn-addled spyware site with the ads and quirky UI/UX.
It was possible to use after some time, but after a week, I noped out and went back to Apollo.
I used the official app too. For whatever reason it always had issues with video playback and comments for me, but I still never switched to another app
I mostly used RiF, but installed the official app during a trip last year to do logistics with someone who was using the built in chat.
I don't tend to always have data on my phone, because WiFi is everywhere, and just add some when I'm going on a trip like this. I'd loaded up a fiver's worth the morning we left, which usually sees me through an entire month in these situations.
Woke up after the first night away to an alert that my data was all used up. And on further investigation, guess which app was the culprit? Just literally sitting there overnight while I was asleep, gobbling up a month's worth of data to do god knows what.
