For those having problems with YouTube on the PS4, use the service's dedicated TV interface in the browser (https://www.youtube.com/tv). I use it every day and it seems to work very well for me.
Getting back on topic, I haven't experienced any bugs with 1.7 yet but PSN has had a few wobbles in regards to the friends list not loading correctly sometimes and party chat randomly disconnecting everyone on the first day the firmware came out. It would be nice if Sony could do something about that, but I appreciate that there's a lot of these consoles out there now and they're all downloading the updates at around the same time.
