[Pro Sites] Pro Sites Upgrades

Every time you release an update to Pro Sites, the software disables site membership. EVERY TIME!!! Ive been bringing this up for over 4 years and its seems the bug will never be fixed! --- Recent update was from 3.5.7 to 3.5.9 and upon the 1st of June, 2018, every site still running on Pro Sites were automatically disabled by the plugin and sent back to Level 0, even after the payment was renewed. This is the very reason we moved from Pro Sites to WHMCS. What is the deal?
