AXE5400 V1.0 firmware 1.5.2

Both routers at current firmware release.

Set the AX1500 in AP mode and tried to connect with EasyMesh. Used all three variants of WPS connection. Tplink lists the AX1500 as easy mesh compatible and has the EasyMesh menu on the left. I've factory reset both routers and have gone through setup several times with no luck. Just times out with WPS_ERROR in system log. Have no problem connecting to either router with WiFi.
