Hello. I’m having a difficult time with the Pro plugin update. The free version was at version 8.x while the pro version was at 5.8. I can get the pro version to update through WordPress, but when I do, it no longer recognizes my pro license and I lose all my custom settings. Is there something I’m doing wrong that the pro plugin won’t update and retain my license?
