The installation process is quite complicated to be honest.
I know this is due to shortcuts, but, creating an account, then wait for a link, to get a PDF on mobile, to install it... what a drag.
I really understand that and I apologize for the friction created. This is mainly due to Lemon Squeezy, as I couldn't include there just the link to the installation shortcut. It required an actual file, but that way I also added the initial instructions inside the PDF, along with the link.
