Solos not refreshing

@Champcrisscross when did you (start to) play your games? I'd guess you either started to play them (i.e. your first game) or did the first opponents update too late.

in order to be able to play all 13 Solo Battle games, you have to start your first game (of the Monday update) before the Wednesday update is released (maybe it is enough to enter the Solo Battles menu, but I'm not exactly sure whether doing this really avoids an automatic update). otherwise you will only see the Wednesday update and lose the opportunity to play the 4 Monday games. furthermore, you have to play all 4 Monday games (except the featured opponent which can be played any time during the week) and do one opponents update before the Friday update is released. otherwise doing the update skips the Wednesday release and you will not be allowed to play the 4 Wednesday games.

I really do not know why this information is not clearly communicated in-game. besides the fact that there is no official information how the skills score is calculated....

I hope that helps you playing all 13 Solo Battle games in the future. good luck!
