Stream app not displaying local Boston Channels 4, 5, 10

The stream app has been inconsistent at best for the past year not showing local channels 4 WBZ, 5 WCVB, 10 NECN.  I’ve had to consistently clear the cache, sign out and sign in and reinstall the app in order for these channels to show up. But today non of those actions results in the local channels showing in the channel guide. Only pages of MLS on APPLE  and pages of streaming. How do I get my local Boston channels so I can watch them live.
