Dear View,
Thanks for contacting us at 505 Games Support!
I'm sorry to hear that you've been having this issue with your purchase of Terraria. If you have local saves, PLEASE DON'T DELETE your app! Like all mobile versions of Terraria, if you delete your app, you'll lose your local saves too. If you have cloud saves only, you'll be OK. We're aware of the issue and are working towards a resolution to this problem so you can start playing Terraria again as soon as possible.
Please accept our apologies in the meantime.
If you need anything else, please feel free to contact us again.
Best regards,
Frederike
