  Yeah, I’m 100% sure they were working fine after the update but before I launched the app and touched the on/off switch there. I only noticed the problem due to the emails here, as the tunnel itself was working smoothly (I only have one per device and it’s on-demand, so I rarely interact with the app itself).

  My initial assumption was, after iOS upgrade, the network extension was able to read the data to create the tunnel, but the app corrupted it as soon as I tried to turn the tunnel off through the app.
