Thanks for the first 2, I suspect my google play version is out of date as those links don't find it for me so I'll just use the browser for now. The play store has no updates so perhaps it's in the provess of being pushed
As for the third, I guess there isn't much of a difference? I'm drawing comparisons to reddit here but there were lots of subs I'd unsubscribe from so they wouldn't appear on my feed but I could still occasionally view them. Maybe it's just me being weird but I feel blocking is bit much for subs that haven't done anything wrong. Ah it's fine though, just me being picky I guess!
I blocked it. Seems pointless
