It seems my bingo task is stuck. It kept rolling back to my previous complete task (keep seeing collect button no matter how many times I clicked the collect).
Even if I tried to start new task, it just if ignores me and kept roll back to previous finished one. I cannot do anything for half a day already.
I have tried clear cache and data already. Nothing change. Before I was lead in bingo leaderboard, now I do not know anymore.
