Manage or cancel my subscription to Wikiloc Premium - iOS

If you want to change any information on the Wikiloc Premium subscription that was activated from an iOS device:

Go to your Wikiloc App > Profile > Settings > Your Products > Wikiloc Premium > Manage Subscription.
You can also access it from this link.
A list of the apps to which you are subscribed will appear, select Wikiloc.
A screen with the detail of your subscription will open. You will then be able to choose from the following actions:

Change the subscription plan.
Cancel the subscription. If you don’t see "Cancel", the subscription is already canceled and won't renew.
Reactivate a canceled subscription that has not expired yet.

If you have problems with the payment platform, this link to Apple's official support might be helpful.
