Why isn’t the squad accurate in my country’s national team?

When we are producing the stickers we are using the most recent reported squad (to Fifa). Then of course squad set ups can (and most probably will) change during the season. Players get injured, players are dropped and others get called up. It is impossible for us to update the team squads every time such changes occur. But for every new season the national team squads will be updated and available for download on the App store.
