Just wanted to share my experience relating to what started as a YouTube message that read “We’ll stop supporting this browser soon. For best experience please update your browser”. I don’t consider myself an LG TV expert, so my only motivation is that this might help someone. The bottom line is there is more than one way to access YouTube on your TV.
First of all, let me be clear that I am referring to the basic YouTube platform, the one that features ads, which is what I use and care for. You also have YouTube Premium (previously YouTube Red), a paid service that offers an ad-free YouTube experience, and thirdly, YouTube TV, which is another paid service that offers live streaming television to compete with the likes of Sling TV and Hulu with Live TV.
For the longest time I watched basic YouTube through the TV’s Web Browser application and it is through this method that I got the “We’ll stop supporting this browser …” message. In trying to resolve this I checked for software updates by going to ‘General’ and ‘About this TV’ where I then selected ‘Check for Updates’ but the system response was ‘No updates found’. My take at this point is that unless LG eventually upgrades the Web Browser application, it looks like this method of accessing YouTube may eventually stop working. It might be a good idea to make sure the “Allow Automatic Updates” option is enabled or checked.
A Second Way (and this how I fixed my situation): I went under ‘LG Content Store’ on the TV, searched for the basic YouTube application and installed it. At first it was a bit awkward to figure out how to navigate the app. but after about 20 minutes of playing with the different remote buttons, I was able to figure it out. As it turns out, this LG YouTube application seems to be more feature rich and is actually easier and more practical to use than by using the Web Browser.
A Third Way: Some time ago I purchased a Roku Streaming Stick+ which also offers the ability to access YouTube. The only issue with this method is that I don’t believe you can use the TV remote to control it (at least I have not figured it out), and for this reason alone, I believe the LG YouTube application is the best solution.
