Hi Chris. I had this problem, too, so I had to reduce the number of tags I was following, including most of my surname tags. I kept or added project tags for my interest in the era/area.
Hopefully, one of the techies will come up with a solution. I have several surnames I’m working on that are common to the UK and the USA, so I had to wade through all of the feed to see if there was a connection to my family.
