[iOS] AirPlay/Mirroring still unusable on 2026.29.0, likely because the app's AirPlay mode now set to "extend" rather than "mirror"

AirPlay screen mirroring/casting from iOS devices (e.g. to an Apple TV or AirPlay-capable smart TV) has been broken for like six months and is still broken in the latest version 2026.29.0 (on iOS 26.5.2 in my case).

The actual problem as discovered by /u/ismoody appears to be that the Reddit app now AirPlays in "extend" (i.e. additional display) mode, rather than mirroring like it used to, as described here: https://www.reddit.com/r/bugs/comments/1thgrtl/ios_airplay_is_set_to_extend_display_not_mirror/

As a result, you simply cannot AirPlay the Reddit app from an iPhone or iPad, because there's no actual way to interact with the app on the external display in this mode.

There have been dozens of posts about this same exact bug over these many months, and the only acknowledgement I've seen that Reddit app devs are aware of the issue and possibly working on it are these comments from Reddit Admin /u/CorrectScale four months ago:

Anyway, it's definitely still broken.
