R6250 with a new problem with Access List

I have used an access list for several years for added network security.  I added a device as recently as 6 weeks ago successfully for a total of 7 devices, however, the device I am trying to add now, a 5g phone, is not allow to connect.  I have had a 3rd party verity mac address, have tried rebooting router, checked for firmwear update with no help. I cut off the access list control and everything connects fine. Any suggestions?  Thanks

      The device I have added to the access list is a Samsung, not an I-Phone and the message of denial is "Device authentication Failure" .  Also it's strange that the router display of devices that are connected lists a mac address that does not match our devices and I feared an intruder but I find that the unknown mac address is actually an I-phone that we do have connected with a different mac address.  This is getting a bit deep for me.  Thanks

        I now see an article that Apple is randomizing I-Phone mac addresses to prevent tracking of the devices, that would explain the non matching mac address on the connected devices.  The samsung 5g phone will not connect if access list in on.
