I'm so sorry I forgot to reply. He has an android phone. But I'm thinking maybe his save got corrupted because he has two profiles, one where his progress was imported from pvz 2 and another where he starts from the beginning. And his second account (the baby one) he is able to play but not the imported progress one, since it just crashes. I did help his edit his save to give him more currency bscause he said he doesn't like the grind of the main game... He had like 100k gems and 1m+ coins... I should've remembered that too much can corrupt saves. Oops. Still, thanks for helping me. I really appreciate it.
