I try to explain the problem.
airport EBBR (no marketplace)
API NAVDATA enable for marketplace products
boing 737 pmdg (but also with other aircraft)
EBBR custom profile
when i start my flight from EBBR (but also in some others airport) with API Enable, GSX cant find parking or gate active.
when i disable API all back working normal.
So, means that i must enable API just when i use product from marketplace?
thanks for help
