Hi there,
I have an LG smart TV OLED65G36LA (LG OS v03.20.17, webOS TV version 8.20.0-710) , and the Prime Video App was no longer able to update (from Dec 2025) and therefore could no longer be used.
I have tried uninstalling the app and re-installing, and that was unable to work, so then applied a full reset on the LG TV and so had to reinstall all of my other apps (Apple TV, Netflix, etc etc) which all successfully downloaded so confirmed network connections and setup are all confirmed working.
When I try to download the Prime Video app, it remains stuck on the download screen and is unable to update.
Thanks
