Hi their,
Two days ago, I had my first post in this lovely community. Got my first Brompton 2 days ago and I already need your help.
It stoped holding its folded position, even though it did it out of the box.
When the seat post is down and I pick it up (gently), the hook on the front tier un clips.
What can I do? Should I return it?
Thanks in advance 😌

Check to see if your lower stop disc has fallen off, it attaches to your rear brake caliper to stop this happening.
I think we need a picture of it folded showing the entire bike.
The nonfolding pedal could be in the way (touchin and blocking the front wheel.
Anyone have a link to a cheap lower stop disc?
Okay so this version doesnt actually have a lower stop disc as a 12 speed. The part that serves the function of a stop disc is actually in the third picture that black )( shaped thing attached on the frame called a locking block.
What you want to do is unfold the bike partially just until you raise up the seatpost. In the side of that locking block is a hole to the screw that both holds the block in place and allows you to adjust it. Use a 4mm allan key (hex key) to turn it anti clockwise no more than a half turn. Check the fold and if its still happening make the adjustment a couple more times.
Watch videos of it
The same thing happened to me with my 12 speed C line. The adjustment that’s shown in this video fixed my issue:
