Lay Theme Forum

Hi there,
I purchased a single use licence in 2018 with the Carousel as an Add-on. Now i want to purchase a second single use licence. In the Add-Ons Q+A it mentions that one can use purchased Add-ons on as many Lay theme websites as one likes. Is this also true for single use licences? So could i use my Add-on Licence from 2018 on my new website i want to buy now and still use it on the Lay theme i purchased in 2018?
