Yes, definitely update to this version. Many things got fixed that were broken in 2.1.2.8h.
My alarm delay bug got fixed, and indeed the activity zones and human only also got fixed.
I have motion sensors, door sensor and eufycam 2’s, so similar to your setup.
Ok, I discovered that when using an ethernet connection the cameras stop working due to this new update. So I adjusted the connection to - sometimes unstable - WiFi to solve it. I do not understand that such updates are not tested better!
Mine is on ethernet since I received it. Have no problems what so ever. Maybe it has to do with your ISP or router? What happens when you set it back to ethernet?
I would hold off from upgrading. Version 2.1.3.3h appears to have turned my basestation into a paperweight! No doorbell or motion detection recordings or notifications. ymmv obv
