Don’t read anything about the game.
Just keep at it. It doesn’t hold your hand at all, and you might get frustrated. Just give it time. If it clicks for you, you’ll experience one of the best gaming experiences of your life.
Check your other replies. This isn’t difficult.
Someone has already responded to you with direct deep links to the settings you wanted.
Sync has been around for a long time and has loads of customisations. If only you’d bothered to go through the settings before giving up, you’d have been able to make Sync your own.
Have you actually tried Sync? It has significantly better UX than the alternatives currently, and the feature list is unparalleled (I’ve really missed being able to filter out specific users or communities from my feeds).
I wish this Sync had the “sort communities list by times visited” option like Sync for Reddit
