2000cs I also have my whole house connected with a ton of various Sonos products straight through my WiFi without a bridge or connect and have no problems. All of my products work on the gold p2 app without a hitch.
The only time I've ever had issues was when I tried a mesh extender, that thing f'd up everything here with every brand of "connected" home devices (Nest, Sonos, Alexa) so I just bought a new extra strong router and started over.
We have 4 floors but our house has a relatively small footprint and my router reaches everywhere. Can your router reach all your Sonos products on its own? If it does, I'd ditch the Bridge and Connect and try it that way.
Good luck
