How to log in into iOS app using sign in with Apple?


New Member
I was unable to find solution and feel dumb. I have a premium AdGuard account and on the computer I login by clicking apple icon and I have access to my account. My license is enabled on 0 devices because when I try to login in the app on my iPhone I cannot find an option to login using 'sign in with Apple' What is Sign in with Apple? - Apple Support
and entering apple.relay email doesn't trigger anything. I bought my license on the site, not in the app so I cannot restore purchase. Not sure where can I find button to login in the mobile app.

Would appreciate any help
