Still having no luck connecting Eero to MyQ app network. I choose the Eero network, type in password and it just idles. I turned off the 5g network, turned off the wpa3 as mentioned above (which I I didn't know was an option). No luck, so which garage door should I replace it with or which product should I replace Eero with? one has to go.

OMG! finally solved. for the Eero device, open up Eero app > settings (bottom Right- notice it is next to Discover tab)> Guest network - turn it on (Tip: use only letters and numbers, no characters for the password). then select troubleshooting and turn off the 5g network. back out of settings by pressing Discover (hint: next to the settings tab), press the eero labs> then turn off WPA3 security. close out of Eero app. Go to your wifi network and connect to the Guest network . Then open your MyQ app.  Start the process of following the step by step instructions on the app. Press the yellow button on your Garage door opener three times and hear the beep. follow the prompts on the app to join the MyQ network. Select your Home wifi network (guest network), type your password. That should be it and it will connect everything together...hopefully!!  This is how I was able to get mine to connect! hope this helped you out.
