Mailbox sensor will only connect to Alexa, not bridge

I have had a mailbox sensor for a little over a year, for the most part, it's worked great, that is until I bought a new Echo 4th Gen. Now the mailbox sensor will only connect to the Alexa, there is no option for the bridge anymore even though it appears in the device list as being online. Even Ring telephone support didn't know how to force the bridge back into the equation. I am trying to unlink my ring account from my amazon account since disabling the Ring skill didn't help. In order to do that I have to remove my Echo Show and Echo Gen4 from my Alexa account, this all just seems like a ton of hoops to jump through to accomplish something that should just be an option in the setup process.Is there a method to allow the mailbox sensor to communicate with the bridge rather than the alexa\ that doesn't require basically starting over? When I re-add the EchoGen4 is it all just going to happen again?The reason I want it to use the bridge and not the alexa is because the bridge is 10feet from the mailbox while the Alexa is about 60ft away in the very back of my hosue, the signal is so low it disconnects and the sensor just stays offline making it useless.
