@Froggsbee I have just tried this and I am only showing a 5Ghz and 2.4 Ghz connection between the BE550 and BE800. I am on the latest firmware for both devices and factory reset my BE800 and the new BE550 before setting things up. I have MLO enabled before setting up EasyMesh. I suspect this may be an item that needs future firmware to enable, but that is just my uneducated hunch.
