I can say that the implementation of the original task is practically possible with results of 50%, as software mass creation of variations in woocommerce is not possible.
The customer accepted this information, and changed the task to another TZ. I agree that it has already become not encouraging to me, since a new task was placed before the fact, and at first it was not considered by me as the possibility was fulfilled by me.
I agree that the initially assigned task was performed by me for half of the function because some functions are not programmatically possible.
I confirm and agree to the refund of the funds to the customer.
