Unable To Access Solo Battles

It seems fairly obvious what's happening, which is what makes the lack of a fix so infuriating. It doesn't seem tied to a particular time, with the exception of the weekly reset. 

1. Players seem to be able, once the weekly battles start, to be able to play as usual. 

2. If players exit the game and then later play again, the solo battles no longer work. Entering the solo battles screen shows a blank rewards screen, which would indicate that the game is triggering the end of the current solo battles early, after the initial play session, but before the actual scheduled end of the weekly battles. That also explains why we all see the rankings screen and also why the weekly reset makes the games available again.

3. The problem for EA is to figure out what is triggering that early ending for affected players. So, can anyone affected by this think of something unique that might have done it? The only thing I can think of is that I usually start with the featured battle, but I've skipped it the last few weeks (I. e. The weeks I've been affected) to play some low OVR teams and try to level up before the season ended.

I hope someone here will post if it gets fixed. I'm done for now. I see no value in continuing to spend time and money on a game that is broken and shows no sign of being fixed.
