hi, I have a problem with registering and upgrading users via cb subs.
I have 4 subscription plans and a couple of products (books) on the site. The first plan is free and during registration I ask you to enter only your name, surname, email and password. The second plan offers only digital products and therefore the fields for registration and/or upgrades are the same. The third and fourth offer physical products (books) included and therefore I also ask for the address and telephone number.
The problem arises if one wants to buy just one book or if one wants to upgrade.
In the first case I register for the free plan (first) and add the book to the "cart" but this way it doesn't require the address. The same thing happens for an upgrade from a free plan (or second without physical products) to a paid plan with physical products (third or fourth). In this case, those who are registered are not asked to enter their address.
How can I solve it?
