iOS app restarts prototype

I’m watching prototypes on mobile during designing and whenever I select any frame in desktop version, the iOS app restarts entire prototype and selects default flow. It occurs even if I select frame in another file. It’s not mirror mode, I’ve selected file in Recents then started prototype. This doesn’t occur in Android app.

iPhone 6s
iOS 14.5.1
Figma 22.0.0

UPD: if I copy share link to certain flow and open it it iOS then this issue doesn’t occur anymore. Strange behavior.
