Did you read the link you posted? They block many facebook tracking components but there are some things they aren't touching right now because some website depend on facebook for logins.
Honestly, blocking ads/trackers on mobile has always been a tricky business. You could set up Pi-Hole on your home network. Or see if there's something similar to this on iOS:

It's actually one of the reasons I use Android and why I'm looking at alternatives, like Librem 5 and PinePhone. I don't like how Apple doesn't allow competing browser engines on their phones and tablets (only skins that use Safari underneath), and I don't like Google's privacy issues on their phones.
