The way it works - first, you max your grid for your main team. You don't even need participation in GO for that, and certainly don't need to be able to complete GO.
After you have maxed out at least one of your teams, then you can do GO and gather that FLB mats.

Unless you have appropriately leveled team & grid, you are not expected to be able to complete GO. However, you still can get rewards from it, you just get less. E.g. I can't complete single one yet, still I've got plenty of Ori to FLB my Phoenix bow.
