When I press the button on my XLOC Full Sprint (I think that is the full name) to unlock the fork/rear shock i get some movement (say 5mm) before a feel any pressure/resistance. I don’t think it used to do this, I think I met resistance straight away, but can’t be sure. I’m assume I need to bleed it, or am I imagining things?

I’m going to answer my own question so others have it for reference. It did need bleeding. It was a simple job (bleed kit came with the bike). I have pressure/resistance the moment I put my thumb on the button now.
