When the expiration date is approaching, the Mistika application will start showing expiration warnings.
If there is a subscription in place, the license is renewed at the same time that the credit card / Paypal is charged for the next period, which happens last day of the previous subscription period.
Then, when opening the application it will get the new license automatically, but it requires internet connection for this. From that point the expiration warning will disappear until next time.
Once the license is in place there is no need for internet connection until next expiration date.
This also means that it is normal to see expiration warnings until the very last day of a subscription period, but that is not indicating any problem with your subscription. You can also check the state of your subscription by login to your account at www.sgo.es/my-account
Thanks for using Mistika
