Two issues i found using tutor lms proversion

Hi everyone, I am new here, i Just bought the lifetime single licence pack Tutor Lms pro, i activated it successfully on the menu dashboard in wordpress back-end. There are still two issues that occurres:
1) When i tried to create a zoom meeting when i press the button “Save Meeting” it gives me the message “Error Request” with the red cross sign.
2) When i want to activate the useful content drip functionality, The section when i create the course it doesn’t exixt.

How can i solve this problems?
