When a user subscribes it activates a scent selector in the user account. There is a different one for each subscription. A user should not be able to subscribe twice and there should also be an option to switch subscriptions. Buying one cancels the other. Currently a user can buy 2 subscriptions and it brings 2 scent selectors into their user account.
1. Make it so a user can only subscribe once.
2. Add necessary buttons into user account to be able to switch between subscriptions. It will cancel one and create another.
3. Test to make sure it works. It has worked before but a freelancer broke it.
