The date of purchase is when releases start archiving. For example, if I purchase a license in January 2019 and time passes to November of 2019, I would only have downloads that were released during that time period.
Although, we can back date a license to include additional archives. I will create this ticket for you and it will be available through your Telerik Account
Please let me know if you need any additional information. Thank you.
