The instructions at the link below are not correct. My understanding is that you need to contact Ring support to change your email address.
That is correct @mmatsuur! Email changes are best done with our support team, over the phone. Please give our support team a call at one of the numbers available here. We’re taking additional steps to protect our team and help reduce the spread of COVID-19, so this has resulted in longer than normal wait times. If you are outside of the US, please read our response to COVID-19 here to see how to contact support.
Thanks. FYI, the tech support agent also throught I should be able to change it in the app. But confirmed that I was not able to do it.
