Exact same thing on the PS4 European servers. Also you get the very typical indication of bad servers on MnB, where when a single message is sent, it repeats multiple times. I've seen it happen on some bad PC servers where it repeats 2-4 times, but here on PS4, I've seen a single message literally cover the whole screen. Messages repeating obviously isn't the issue itself, but you can take them as a measurement of the server-client issues present on the server. Also the servers didn't appear to suffer from these issues when I played it around launch.
Edit: Well while I was testing it today, everyone disconnected so I think the servers were reset. I rejoined and it appears the issue was fixed. Significantly more responsive, and the combat has been upgraded from the laggy spamfest it was a few days ago (Despite reporting good ping). One job Taleworlds. I actually remember near launch the servers would sometimes go on and off. If that is the solution to keep them maintained, you should reset them regularly.
