Bought a new 65" Smart TV, all the preoaded apps You Tube, Netflix etc are restarting after couple of minutes with "this app will now restart to free up more memory" message.
We had the same issue. Unplug your tv and press the on/off button on the tv, hold it in for 10 seconds while the tv is unplugged. Then wait 20 seconds more and plug the tv back in and turn it back on. This solved the problem for us.
