iOS: Geohash teleport field immediately loses focus, cannot type

Bug description

On iOS, the #geohash field in the teleport/location-channel UI appears grayed out. Tapping the field briefly focuses it, but it immediately loses focus before any text can be entered. This makes manual teleporting to another geohash impossible.

This previously worked for me, so it appears to be a regression or a state-dependent UI issue.

Steps to reproduce

1. Open bitchat on iOS.
2. Open the location/geohash channel picker (the UI used to teleport to a geohash).
3. Tap the #geohash input.
4. Observe that the field immediately loses focus / the keyboard cannot be used.

Expected behavior

The field retains keyboard focus so the user can type a valid geohash and teleport to that channel.

Actual behavior

Focus is dismissed immediately on tapping, preventing any text entry. The #geohash row appears disabled/grayed out.

Environment

• Platform: iOS (iPhone)
• Distribution: App Store
• Latest U.S. App Store version as of October 23, 2026: 1.7.1 (July 31, 2026)
• iPhone 16

Additional context

• Another iOS App Store review has described a similar symptom where the keyboard disappears when attempting to type a new geohash; it's not confirmed to have the same cause.
• Potential area to investigate: view refreshes, tap gestures, sheet state changes, or focus-state handling in the geohash picker. These are hypotheses, not a confirmed root cause.
• A deep-link or bookmarked-channel workaround may bypass the text entry, but that does not fix the UI.

Thanks for taking a look!
