Greetings, lords around the world!
This is GM Lumisade

There is an issue where the 'Purchase Canceled' error message popping up
when you try to make a payment in the shop.
If you get the message, please restart the app or press 'purchase' button again
and it will be sent to your inbox.
(You don't have to worry since you won't be charged again.)

Thank you
GM Lumisade
