The latest build has broken all TVE CBS News and CBS Sports HQ, CMC's and NBC News Channels. Logo’s disappeared making them not selectable to watch via web browser
Same here, MLB and YES networks are not working on mine too.
I deleted and re-added YTTV and performed a new channel scan and lost a bunch of channels. I am running version 2020.01.19.2104
Channels now reporting scan error 'failed: notAuthorized':
FS1, FS1, BTN, MLBTV, UNIVERSO
Channels now reporting scan error ' encountered exception 'Uncaught' (5:5)':
TLC, INVESTIGATION-DISCOVERY, TRAVEL
I am able to access the channels above directly on the web using my YTTV creds.
Sorry, but how do the three replies here so far relate to the OP’s posted issue? 
This issue was fixed with build update on Saturday. I don't know why anyone included YTTV in this forum. I don't have YTTV.
Any questions on YTTV TVE access should be found here.
