I'm having that issue on All, I can view Subscribed ok at least. I assumed it had something to do with me filtering out Trump but it's good to hear it's not just me.

Try logging out. I recently had this issue and I could scroll down logged out, it logged in to any account both on boost and jerboa meant no infinite scroll.

It's fixed now, but I don't know why it broke nor do I know what it's fixed. Maybe you have the same issue.

I determined that it is a problem with lemm.ee pagination. Even on PC the next page of post takes a looooong time to load. I think Boost's internal timeout is too short for the extra long load time. So I switched instances and every runs very well.
