Chat apps and microblog apps handle relay selection very differently. Microblog apps tend to use as many relays as possible to avoid missing any notes. However, chat apps don’t require that many relays. How many message relays are you currently using?

Chat relay, yes. Let me put it this way. Suppose I have set up relay on my laptop/phone (i.e. Citrine), and we need to have access to it from the outer world. But IP address constantly changes, so I’m doing some Dynamic DNS, thus it is needed to update relay list in, say, 3-4 hours.
