Steve. Just to confirm as well (in case I haven't mentioned it before lol !) I have no issue streaming BT content including UHD Red Bull content. And Amazon and Youtube 4k content is totally fine. This is purely Internet TV channels for me.

Not in our house, either.
Mrs Essemess just checked some SD & HD channels again (329, 430, 370). All immediately unwatchable. 😞
