Trying to play apple tv in chrome and get audio but no picture

I've recently subscribed to apple tv+ (streaming). For the first couple days it worked fine streaming thru my browser (chrome; PC). Lately, sometimes it works, sometimes it doesn't. Mostly the latter. When I launch apple tv+ and click on a choice, I hear audio but there won't be a picture. I've tried signing out, clearing my browsing data, restarting my machine, etc, etc. Sometimes this work (but will take several tries) and many times it doesn't (like tonight). Also, where's the search function? HELP! Please.
