Hi there! Looks like you linked to a Lemmy community using a URL instead of its name, which doesn't work well for people on different instances. Try fixing it like this: !veryrealtechpics@lemmy.world
This is the second time in like 2 days I’ve seen someone complain about Boost missing some super basic functionality. The other one was someone asking the commenter to post a link to a photo instead of embedded in it since Boost didn’t support zooming in on embeds. Maybe Boost is just a bad client lol
