If you want to not miss anything, switch from Subscribed to All. Also, check if your instance blocks any others by scrolling down to the bottom of the page and clicking Instances.
To add to what @goat@burggit.moe said, blocking instances isn't necessarily a bad thing. The trick is to be on a server with a blocklist you agree with. If/when there's some kinda extremist alt-right instance focusing on finding and harassing people of specific ethnicities, for example, I'd be very disappointed if my instance didn't block it.
You should actually install Jerboa mobile client if you are on a phone, it's just so much better than the web interface. But on a laptop, the web interface is pretty good.
