Sorry I'm new at here, but I red and saw all rules and videos, but when I put my client ID and client secret, tap "save" and "get auth", I can choose account and after that I see the error "400: invalid_request" from Google and said "The application cannot be signed in because it does not comply with Google's OAuth 2.0 security policy". I didn't find how can I fix this.. Please, help
UPD: I did it. Just tried go in system (button "auth") without typing client ID and client secret and chose my account. Then it gives my auth code. I'm so happy, cause I tried to find this course like some days and was so upset..
Thank you for your job!
