I'll be honest I revanced the RIF app so i can still use it like I always have for the time being until it breaks.
I don't notice much difference, but since using Lemmy it's really made me notice how crap Reddit had actually become. I genuinely check Lemmy more and post more here. It's more engaging and so far the people are nice. I'm still new here tho and still finding my feet on navigation etc but it's making a lot more sense now!
I probably will still check Reddit on RIF whilst it still works as I do like the niche subs and they are still active for me. I did initially try the official Reddit app and jesus what a mess that is, I will not use it once RIF permanently breaks. So I'm still there but more lurking than posting.
The tutorial works for me as well, but keep in mind that RiF is not being actively developed anymore, so as he said you can still use it until it breaks.
