LG G1 streaming problem with latest software

[Nick Payne]

We've had a 65" OLED G1 for a while (Australian model OLED65G1PUA.AUS). No problems with it until the latest software update that installed on it a couple of weeks ago (the set shows the current installed level as 03.21.05). Since the update, when streaming using one of the apps built into the TV, maybe once every couple of days the picture will freeze in the middle of playback, and two or three seconds later the TV kicks us back to the initial screen for the app that we are streaming from. We've had it happen with Binge, with Apple TV+, and with Amazon Prime. If we access the same streaming services using the Android version of the apps on a Chromecast with Google TV that I have plugged into one of the HDMI ports on the G1, we never see the same problem.

As the problem doesn't happen with the Chromecast, it doesn't seem to be a network problem (both the Chromecast and G1 are using a wired Ethernet connection rather than WiFi); as it happens with multiple apps on the G1, it doesn't appear to be a problem with a specific app; and as it has only started happening since the software update to the TV, that points the finger at that update as being the cause of the problem.

Any suggestions? There doesn't appear to be any officially supported way of downgrading the software on an LG set to the previous version to see if that gets rid of the problem.
