Detection zone won’t save - Cam V2

v2 4.9.9.3006 Android app 2.50.2.442

I made a minor revision to a nicely functioning detection zone, seemingly without issue. Saved and rechecked just like the OP.

Realize five days later that I’m not getting any detection notifications at all on this not-that-active cam.

Check zone: a single square at the top left corner is all that’s active. Revise, save, back-out, back-in: Zone seems to save but doesn’t, the top left square persists.

Power cycled cam, reinstalled current app, same result.

Installed a prior app, several versions back - 2.49.1 (390) - no joy.

Recommendation: Do not make a minor revision to the dodgy v2 zone. Live with what you’ve got.
