I was not sure if I should post this in the iOS section or here since its about LR support.
I noticed the new build of the iOS app (253) has LR boot mode as an option.
I scanned in a ZEN37 and checked the SS endpoint list, it shows as boot mode 2 (LR).
In the mobile app if I open the entry it shows as Smart Start (regular, mode 1).
I also scanned a ZEN52 which has LR support via a firmware update. That scanned in as regular SS, shown in the endpoint and the app. I edited it and changed it LR boot mode. It shows mode 2 in the endpoint now, if you re-open the list it shows regular SS mode again.
So... long story short, the LR boot mode is there and you can change a device to it, but it is not showing it correctly when the entry is in boot mode 2, it still shows as regular SS.
@moncho1138 Can you see the beta section?
