Or the relays are being slow. I use Damus too. I’m not an expert. I’ve just seen empty feeds and if you look in the top right there is 0/57. I use 57 relays. So I think that means it’s receiving no data from the relays at that time. Then if I switch over to my relay list all the relays have a spinning loading icon. Typically if I give it a minute they connect. And then messages appear in the list.
