DataBase Import Fails on Nougat (and marshmallow)

[TecMunky]

The xDrip app fails to import database.

Nexus 5X or Nexus 6P (Android N on both)
•importing database results in absolutely no data
this previously failed when these devices had marshmallow installed

I get no data records at all when I try to import database on the 5X and 6P.
The import appears to succeed, but no actual data is imported.

For a logcat capture, I would need some guidance. I tried to capture one using Android Studio, but when the app gets installed on the connected device, the app crashes.

I can start logcat from the adb shell, but I don't know what command to use to filter data from xDrip only

I discovered that if I import the database, then immediately import settings - that I get all the data back. So while this is somewhat of an issue, it is no longer as important as it once was.
