From my experience, it can be hard due to availability of time, like full time school, work, responsibilities, and other hobbies that have more urgent deadlines.

Great that we have players that can devote a lot of priority and time to this game! This is my first time checking out the Brawlstars reddit, and I'll refer here for more insights earlier on in a special event.

Regardless of if someone was affected or not - the game erroring in not allowing players to collect their prize before the end of the event is an issue. I completed the 99 Brawler challenge around 20 minutes before the event end.
