If anyone else have this problem you can try this.
Before you read. I am on Xbox. This solution may not translate to PC.
When trying to load my flight plan in to the EFB, the EFB says that I need to enter my pilot ID (even though I have done it).
When spawning in Sweden the EFB settings are on metric. In SimBreif I have feet.
I changed to imperial on the EFB and then it loaded in the flight plan just fine.
Seems you have to have the same measurement systems in the A320 neo v2 EFB settings and SimBreif to make it work.
