iOS app improper handling of reserved Keybase URL

If I want to verify a message someone sent me on iOS and I click this link: https://keybase.io/verify

I am redirected to “Error loading profile: not found” in the Keybase app because the Keybase app assumes it’s a user when it is not.

Reproduce the issue on iOS by opening https://keybase.io/verify and observe the app's profile-loading behavior. Trace how this reserved URL is routed, then verify that it reaches the message-verification flow instead of showing “Error loading profile: not found”.
