Ok, we'll have to take a look and report back.
It sounds like many people have this exact same issue with contact lists not being updated. Maybe a caching service issue? Thank you sir. Appreciate it.
We can't seem to be able to repro this. Contact list updates by other clients appear to be correctly picked up by Primal. Question: are you seeing this issue only on the Primal web app, or also on Android?
Web and Android. I'm only following 3 people on Primal. I am following 1400 in other clients. I'll try to unfollow and follow people to make changes to the contact list.
