Forum is suddenly different on my phone?

Starting a few days ago the forum is now viewed in a new format on my phone compared to the old full site format that I can still view on a PC. Even if I go to “full site” at the bottom it still comes up the same. Is this an update or something automatically done through phones? I don’t find it very user friendly and it’s hard to navigate. How do I go back to the old full website?

Mine has been like that for ages %80 of the time I have to scroll down to the bottom & click the link for the full version .

Mines still full site on iPhone

mines that different one to the full site on my phone i dont mind it

You youngsters and ya phones.....
