bally sports north on analog TV with Comcast box connected-Minneapolis

I posted a question yesterday but forgot to mention my location: Minneapolis (western suburbs).  I have some old (fat) analog TVs with official Comcast boxes connected, and the services have worked well for years. My analog channel on these old TVs with the Comcast boxes has been 28.  When BSN stopped broadcasting through Comcast in May, I got the purple screen saying "not available" on both my analog TVs as well as the smart and HD TVs in my house. Now that Bally Sports is back, on my analog TVs, Channel 28 has disappeared completely. I have powered off and on all the analog Comcast boxes, no effect. When I select Channel 28 on the analog TVs, it goes to Channel 29 (Golf Channel) and I can manually scroll down, which takes me to Channel 27. The channel guide on xfinity website still shows Channel 28 for Bally Sports North. If I select Channel 28 on one of my modern TVs, it accepts it as valid and re-directs to an HD BSN channel (such as 863). I subscribe to the ultimate tier of service and BSN is part of my package. I get all the other premium sports channels on my analog TVs. Channel 28 for BSN disappeared when Comcast resumed BSN broadcasts on 8-1-24.
