Trying to re install my Ring video doorbell

I’m having issues getting my WiFi to connect. It’s never had a problem until I changed my router. Once I changed ring wouldn’t work. I was told to go to the app and click on reset. There was no reset under the devices health. So I went to help and was told to set it up again. Once I did that the device was no longer listed in the app. Once I tried to set it up at the end it tells me I’m not the owner which I am and it’s only ever belonged to me. My wife is a shared owner so we deleted it from her app and then tried to install still getting this stupid message. Tried to log onto ring.com and it wants to send a verification code which sends me back to the app. I just want to install this bloody device and be done. Someone please help!
