I have 2 kindle fires I'm trying to set up. When I enter the 10 digit meraki code in the Meraki SM app I am immediately prompted with a login. The app does not say which account it's asking for but I assume it's my gsuite account that's tied with meraki. It has 2FA set up and I've tried both my normal google account password and an app password I've generated. Both fail with a login not recognized. I even tried my meraki login which returned the same result (Meraki also has 2FA enabled).
I'm not sure what to do here. Are all kindle devices unsupported?
I re-read one of the pages you linked and the solution was stupidly simple. This is a kindle, it's not able to run all the google services I tried setting up (I'm tied to a google apps domain). So I went into the Meraki users dashboard and made a new meraki user. I signed in with that account and was able to add my Fire. Which means I'll be able to add the other one later.
