I’m running ipCam on an old 4S (as a webcam it’s a good image!).
On restart after the latest update 5 days ago (?) the app no longer runs. Screen flashes once then app disappears. It’s still in background as I can see it via Home button, but if selected it closes/goes to background immediately and doesn’t respond to external http requests.
Disappointing!
