josef_nikolause68526452, Good evening. Although it is possible to change from a single plan to All Apps, it is necessary to cancel Acrobat, so consult with customer support. If you cancel online, depending on the plan, you will not only get a cancellation fee of 50% of the remaining period, but you will not be able to switch because the plan can be used until the next billing date, so do not cancel Please! If support is out of business hours, you will need to discuss the circumstances on the next business day and discuss whether Black Friday is applicable.
