I've had a LG OLED55EPUA TV since last summer that has been pretty good most of the time. However, I've gotten rather interested in streaming content from my Amazon Prime account and the app is proving to be a real problem recently with error messages which don't say anything. The image freezes a lot. At first I hit Back, waited for a moment and then hit Resume but after a while that failed to fix it. Increasingly, I have tried stopping the app under Recents on the Home screen, backing out and coming back in - used to help but not anymore. The only other options I know of are: 1.Shut down the TV, unplug for a minute or two and plug back in. 2.If there is an update to the app I would install and that has helped the few times one comes along. What to do if there is none – uninstall then reinstall app? 3.I couldn’t find it but is there a “restart” function to these TVs? The only related setting is to reset to defaults which I would really rather avoid. A real drag to put back all my settings – which I took the time to document when first set up! Problems like this are one of the major reasons I think streaming is a VERY poor substitute for cable TV and physical media - still unreliable in my view. Any constructive input would be welcome.
