My TV : 55PFL6007 2012
Soft updated.

When I want to see video on you tube from smart tv app, there is no problem with short video under 30 minuts long (I dont make test to know when the problem appears). But when the video is longer, about 2 hours and more it's impossible : the screen is locked, the "working progress" round logo stops to move, and usually, the TV shoot down and restart, but sometime not (I have to restart smart tv by pushing smart tv bouton on the remote control).

This problem become some month ago because, I was able to see 3 or 4 hours video long before. Do you make an update of the soft in order to locked long video on smart tv you tube apps? Could you hep me to get back the possibility to see long video?

I don't change anything on my network connection from the beginning.
