I've been getting this via email. From what I can see I only use this for the Google login. Do I have to pay for this now?

 

I'm thinking you'd probably want to raise this with Google?

I would advise checking your billing to see what you have enabled. The Google Maps integration does cost money, however, they provide you with monthly credits. The Google Login from what I can tell does not cost money.

You'll want to contact Google if there are any questions with what is going on here though.
