Xfiniti Pods 3pack stopped working - slow blinking lights

Pods were working with the router for a year with no problems.  Few days ago all 3 went offline, and are blinking slowly.  I tried unplugging - plugging back in, restarting the router, removing the pods from the xfi app, and tried to add them back via the app.  After removing them from Xfi I cant add them back on (setup from the Xfi add fails using Blutetooth and using direct serial number)

How can I remove the POD registation from the cloud to re-set them up via the Xfi app?
