Dear Team,

thank you for developing a great Telegram client! It has a pretty good UX.

However, the big thing changes since iOS 11 released tremendously affecting UX -- SFSafariViewController stops share cookie with Safari.

The problem was detailed explained by the Branch team.
For all developers who uses Telegram for distributing links to users it means to kill ability to match the user e.g. for deep linking.

Could you please avoid using SFSafariViewController?

I think this protects privacy very well and I do not want Safari and the app to share cookies

@yknext, thanks for commenting! I agree, it absolutely make sense for privacy as it was before iOS 11.

However, let's agree that there is no vulnerability if it restrict per domain only, i.e. the domain www.example.com will see the only own cookies within Safari and within the app.

On other side, it will bring a better UX for user in terms of sharing session between an app browser (in particular, within Telegram) and Safari.
