Switching from a monthly subscription to an annual subscription

I would also like to know this. I cannot find it in the learning center.

If you want to switch from a monthly subscription to an annual subscription for Dexxter, you can do the next:
1. Go to "Settings" > "Subscription"
2. Press the red button "Cancel subscription"
3. The current monthly subscription will remain enabled until the end of the current period and will not be automatically renewed.
4. Once the current subscription has expired, you can select a new subscription, just like at the beginning (monthly or yearly).
5. After the current monthly subscription has expired, you will revert to the free version of Dexxter until you select a new subscription. Dexxter keeps all your data, so when you renew your subscription, everything will be available again. Great!
