After the end of the battle pass season, all my xp boost rewards have been sent to my mailbox (I didn't get any of them).

Since a few days, I can see that there is no more XP boost in my mailbox, what happened? It said available for 99 days.

I have currently no XP boost activated and, since the end of the battle pass season, I've used:

• the 3 days XP boost offered for the Easter week-end
  
• 1 or 2 XP boosts from the weekly rewards
• and maybe 1 XP boost from the battle pass season

Thanks for you help.
