For what its worth I was able to log in today on Atom after whatever happened with boost. So it can work, might be worth trying again

I just installed Atom for reddit, it's pretty barebones but works for me

This makes me so happy. It's honestly (one of) the main things lemmy is missing right now - a highly polished user experience. All the mobile apps ive tried have a ton of problems, the web interface is aight. Boost for reddit is (was in a couple hours) the best reddit experience available. So i have full faith this will become the best lemmy app available.
