Eero Pro compatibility without Ring Alarm Pro

I just upgraded to an Eero Pro 6e router and cannot get my doorbell or outdoor camera to connect to the main network. They both connect fine to the guest network. There were some older threads about this that are now closed with the official solution from Ring being to just buy the Ring Alarm Pro. But I don't want a Ring Alarm Pro, I want my existing Ring products to work on my main wifi network. It is mind boggling that this is an issue considering the Ring Alarm Pro has an Eero Pro built into it... Why are my devices having issues with a regular Eero router?
