Question about LG 65uj634

The Zattoo TV app seems very neglected. Zattoo cannot be rewound or paused (despite a premium account; it may be my fault, but if you google the Zattoo Smart TV app, you will see that the app seems to have been neglected).
There were also always interruptions and the picture quality fluctuated greatly.

Wilmaa is unfortunately not available on the operating system. That's why I bought an Apple TV to go with it (and no, this is not meant to be surreptitious advertising).
Apple TV in combination with the TV can only be recommended. Nothing against the TV, but it is even better with Apple TV!
It also allows you to use Wilmaa, which was the reason I bought it. No interruptions, super stable connection and a razor-sharp picture. Pausing; fast-forwarding and rewinding etc. is all possible and easier than ever with the Apple TV remote control. (And no. Still no surreptitious advertising; simply a super product and I am completely satisfied with the combination).

Hope your question is answered.
Kind regards
