Missing rewards at challenge championship

i defeated the challenge championship and i take the rare kandy but it says that i won an iv stone and a dream mist but they dont appear in my items what happen ?

where is the bug section ? i see only general discussion and could not find the bug section because the battle frontier is realy bugged for me.

Challenge Championship is still bugged

IIRC there is no designated section to report bugs here on the forums. Also, you’re not the only one with these issues, basically nobody gets rewards. The entire battle frontier is just super bugged. Keep waiting until a patch that fixes it comes out.
