I was planning to use Gumroad to sell software license keys for a service I am developing. Recently I wanted to check some things and I found out that the help / documentation pages are missing. These used to be very complete, including a lot of information on how to setup products and services, questions about taxes, payments, etc. Now everything seems to be gone, and the documentation seems to be replaced by a "demo account" which includes some (very basic) demo products (https://gumroadhelp.gumroad.com/).
Re. software licenses, the only mention of them in the whole site is a brief line in the "Features" page (https://gumroad.com/features), which says: "Generate license keys. Selling software? We can create your license keys, so you can get back to beta". And that's it. Not very helpful.
Anyone knows what has happened? It doesn't make much sense to replace a lot of existing, useful documentation with a simple demo account.
