Just joined lemmy today and am using the Jerboa app. It took me a bit to get logged in, the “instances” confused me. But I was able to customize my feed to look like what it used to on RiF(been using close to 10 years).
I second Jerboa for android users who were comfortable on RiF
I prefer using DDG or Firefox, however my device I lower end and I find that Brave works best on it.
But I use DDG for my search engine.
