Yeah, so, uh, m.facebook.com has made a sudden and radical change in the last few days. I'm not sure what's going on, but it's currently not usable for me. I don't know if that's happening to multiple people.
I use Friendly social Browser on Android. It's basically a wrapper for the mobile website and allows me to sort posts the way I want them, which is important to me. I don't want the algorithm. I've used it for years. It works with quite a few different social media sites and doesn't allow all the tracking. I have the Plus version and I'm allowed to turn off ads on both the app and Facebook and block "stories" and other silliness I don't care for. I don't know if the free version does all of that.
