Latest IOS app and defaults

Can I just get someone else to confirm that in the latest IOS app the External cameras, time between captures does NOT default to 1 sec and if you set it to 0.5 it NEVER sticks. Seems the default is 0 seconds.

Just did an hours drive and got no images despite the app interface telling me I was recording and showing cumulative image count increasing. Also got 0% battery level (despite it being at 100%)

App version 4.8.20, Ipad Air 2

Mine was set at 1sec default (6s), but I used distance-based capturing
