Hi Dirk,
First, let me thank you for your lighting response.
I will ignore the red bar and frightening message .
My Android device is a Galaxy S7 Edge 32GB, model No SM-G935F, running Android 8.0.0
Knox version3.1, API level 25, TIMA 33.0
Kernel version 3.18.91-14843133-QB28500905,
Subsurface-mobile Android app version 3.0.5 (4.9.3.1486)
I hope that is enough data, if you need any more, I will try to supply
Crash at 19:33 Wed 13 May,
And another one after a phone reboot at 19:48
it throws me out just after it prints 'Finish populating data store' on the screen
I am in the UK for the timezone.
Regards
Richard
