Disable APO from Cloudflare


I need to disable APO from Cloudflare for optimization purposes. Optimization people still insist that APO is working even if I disable it from Cloudflare Plugin at wordpress

"We are currently unable to complete the optimization because Cloudflare’s APO is still enabled. This is shown in the site’s headers:

CF-Cache-Status: HIT

cf-apo-via: tcache"

APO is still at headers. I need help on this.
