Bookly Pro v2.1 is required for the other addons to function
Current version in the repository is Versión 2.0
My Bookly from here worked well. I have not updated them too. They are 17.5 and 2.0 for the bookly pro.
But now it says: “If you do not provide a valid purchase code within 14 days, access to your bookings will be disabled.”
Do you have this problem too?
