Today we released a new version of our HeliumTracker mobile app.
This version fixes issues with In App Purchases so it is important to update before you purchase a membership through the app.
In the old version it happened that some of you bought duplicate memberships and paid for them twice.
Unfortunately, we cannot actively refund duplicate payments. You have to request a refund in the AppStore or PlayStore, which we will of course refund.
If you are affected please open a ticket in support with your UserId so we can fix your account.
