Comcast Canton, MI channel lineup mismatch

As of 4/27/17, Comcast has shuffled stations around on its Canton, MI lineup. It no longer matches the TiVo lineup, preventing me from easily programming recordings and passes. Is there a way to manually force an update, or does it have to come from Comcast? Both Premiers and my Roamio (3 TiVos in total) have connected today with the service, so it's not a connection problem. Any help would be appreciated.
