I've been playing this game for years and actually still really enjoyed it but about three months ago I got a new phone and ever since I've not been able to play hero challenges at all, these are really needed to get the hero fragments and without them I'm not able to level up the new characters to the level where they can be useful and it's causing me to fall behind. I've messaged customer support several times but nothing has been done so I'm not sure how much longer it's worth playing anymore
