Cannot remove jetpack’s inserted //i0.wp.com/ from source html output.

I’ve used Jetpack’s CDN for a few years. I’ve now decided to use a different CDN.

I’ve unchecked Jetpack’s performance features and disabled the image and asset CDN.

Refreshed caches etc, resaved paged and widgets.

However, ALL the site’s images still have the //i0.wp.com/ prefix in the source HTML output. This isn’t isolated to one site – I’ve experienced it with 5 sites I’ve been working on that use Jetpack.

It seems to be impossible to remove the inserted image url references to jetpack/photon.

Do I have to redesign the entire site and upload all new images to remove the inserted //i0.wp.com/ references, or is there a better way?

Would appreciate your input. Thanks.
