Transitioning in purchasing/buyer/logistivs

Quick run down
18 years managing people
10 years customer facing
8 years warehouse logistics management, purchasing
4 years of college no degree had to drop out to take care of my siblings due to family tragedy.

Currently a warehouse manager in the food and beverage industry.

I am looking to transition into supply chain logistics either as a buyer/procurement manager/ or related supply chain fields.

After 18 years in the operational side of things the old body is breaking down but the mind is still whip sharp and I would like to use that in a supply chain logistics role. I have
My resume out there and have 3-4 interviews but don’t seem to be breaking through. Any advice for someone in my position? Anything I should emphasize in my resume?
