challenges glitched

You played challenges from the next week that were unintentionally already set online.

Btw. could it be the same with Legends? ... Week 1.5 challenges were available right after launch - but are not there anymore?

@GodVanHagenFMmaybe, but there was also a glitch with the last challenge in this group.

Still dealing with this, ultimate boom challenges are unavailable to me. Probably because I finished a bunch of them while they were temporarily unlocked.  Now I can't do solo battles either, no opponent lineup whatsoever.
