@LizEllie I think creators have the right to protect their goods. As far as I know, the process of using the authorization system is very complicated and troublesome.
And you can still apply for a refund, but there must be a reasonable reason, because the refund of virtual products itself is an unreasonable transaction for the creator, because you have obtained his file, but you do not have to pay a dime money LOL
So I can understand this approach, just make sure you are prohibited from exporting packages
