Can't capture https traffic to Microsoft B2C login

[PAVEL]

In Fiddler Classic decryption I set <client> and tls 1.2, I'm capturing traffic from mobile application via Fiddler proxy working in local network on Win 10 machine,

but still B2C in Safari shows me message "This Connection Is Not Private", and says it shows this because site uses tls 1.0 and tls 1.1;

is it solvable?

In the beginning I had only tokens: <client>; ssl3; tls1.0; tls1.1 - but then I added 1.2, should have I reissue certificates ?? (suppose that not)

What can be the issue?

Thank you much.

Actually what I see now is that no traffic from mobile browsers on my iPhone is decrypted, and browsers even absolutely refuse to open pages. BUT - from some applications HTTPS traffic is correctly decrypted!
