You can’t test on Sundays or Mondays, there is a practice requirement too that requires three days of PvP, three fights per day. The practice requirement check resets each week, on Sunday.
Also can’t test until one week has passed from when you got Jounin.
The dates I’ll be unavailable to test are in the announcements channel in our Discord. If you don’t use Discord, i’ll post it here, if not in our discord, discord link is in-game through /discord
