If a plugin is upgraded to a newer version (like bx_digital V2 to bx_digital V3) while you are making your PickPack payments, you will not immediately become eligible to upgrade to the newer version for free. The reason for this is that while you are in the process of making your monthly payments, you are renting the plugin and do not yet own a full license for it. Once you finish paying off your PickPack, then your licenses will be converted to regular full ones and you will be able to receive free upgrades on the plugins that you now own.
However, we will be offering users special deals on upgrades to newer versions when they become available. So please be sure to be signed up for our Newsletter for more info.
