[iOS] Sharing to Keybase takes you to the app

Since the last update on iOS, Keybase opens itself when I'm trying to share links with people and then tries to show a dialogue (which breaks, if I tap it during the ~second it loads, requiring me to go back to the previous app and share with Keybase again), where it asks me if I want to save the link I'm trying to share as a file.

Please don't open Keybase when I'm trying to share a link with somebody. The previous UX was amazing and allowed super quick sharing. Now it's slow and tedious and a pain to use compared to any other e2e chat app.

Reproduce the iOS share-link flow described in the issue and compare it with the previous sharing behavior. Done means sharing a link sends it directly to a person without opening Keybase or prompting to save it as a file.
