PS5 locked at 25fps despite Boost

[lorcantc]

I'm watching Sky Sports on the Now TV app, and I've got the Boost, but even though I've got 1080p and surround sound, the 50fps sports channels are at 25fps. Is there a fix? I've tried talking to about 6 live chat assistants and each one has been utterly useless

I’m pretty certain there is an issue with ps5 and 50 FPS might be wrong but sure I saw it somewhere.
