No, there is no grace period available. We’re offering an upgrade license for 50€.
But before sighing of disappointment, hear us out. You paid 149€ for soothe (or even less if you bought second hand or during a sale). A full license for soothe2 costs 199€. The upgrade deal of 50€ brings you level (or even less) to what you paid for soothe. No one is losing any extra money here!
