A WithU free trial is included when you choose an annual membership.
In line with App Store and Google Play Store policy, upon starting a free trial, your card details are registered to verify your identity and ensure you can be charged automatically if you don't cancel the subscription before the trial period ends
We highly recommend cancelling at least 48 hours before the end of your trial period, so any delays in the App Store / Google Play Store processing your request will not lead to you being charged.
If you didn’t cancel your free trial before it ended, then your selected WithU membership will have started automatically.
