Please, what is the name of the chrome extension you are using ?
I got on online chat support yesterday. The agent said he refreshed the online tv guide for my feed and swore I wouldn't have the problem again ... and I didn't for the evening. But today it's same-old same-old non-loading of the program guide ...
Granted the problemo will get solved -eventually- HOWEVER I am $paying$ for it to work, not to pay to be a beta-tester.
