I have a problem with purchasing access to integration with Booking.com or iCalendar. What should I do?

Integration with Booking.com or iCalendar is an additional service and requires an active Premium license on any platform (Android or iOS) in order to operate. If you want to purchase Premium access for an additional service, you must also have Premium access on any platform (Android or iOS) for the same period of time.

It is not possible to purchase Premium access for integration purposes (Booking.com or iCalendar) for a period of time longer than the Premium access period for an Android or iOS platform. Examples:

EXAMPLE 1.
1. 14 days of Premium access remain on your account on a given platform (Android or iOS).
2. You want to purchase Premium access for integration services (Booking.com or iCalendar) for a period of one month.
You can't purchase Premium for integration services (Booking.com or iCalendar) without extending your Premium access on one of the platforms (Android or iOS).

Solution:
1. Purchase Premium access for any platform (Android or iOS) for a period of one month.
2. Purchase Premium access simultaneously for the additional service (Booking.com or iCalendar) for a period of one month.

EXAMPLE 2:
1. 3 months of Premium access remain on your account on a given platform (Android or iOS).
2. You want to purchase Premium access for integration services (Booking.com or iCalendar) for 12 months (in order to obtain a 10% discount).
You can't purchase Premium for integration services (Booking.com or iCalendar) without extending your Premium access on one of the platforms (Android or iOS).

Solution:
1. Purchase Premium access for any platform (Android or iOS) for a period of 9 months (3+9=12).
2. Purchase Premium access simultaneously for the additional service (Booking.com or iCalendar) for a period of 12 months.
