Hello, I use Amelia plugin for my website https://kalimah-center.com/ my website is an online Educational website. I use packages to allow customers buy bunch of lessons instead of single lessons. I disabled the rescheduling option of lessons because it gives  the customer the ability to reschedule lessons to 30 days in advance (Days of booking in advance) regardless when the package expires. It just calculate the days in advance from today even If the date of package expiration is tomorrow.

I can give an example; 

Student (A) bought a monthly package of lessons at 3 Jan 2022. It should be available till 3 Feb 2022. At 20th of Jan 2022 the student tried to reschedule the lesson.  He found that he can put the lesson from today till 20 Feb 2022 without considering the Expiration date. This affects me badly as a monthly package can be used for up to 2 months. Please fix this as soon as possible. 

Another thing I suffer from: 

When a student books a package but he doesn't  choose all appointments at once he also finds that he can book 30 days in advance without considering the Expiration date of the package.
