It's funny in retrospect that people here recommend using pieces of
melamine with clamps while gluing up a project, specifically for its
"glue-repelling" qualities. Oh well.

What should I use this time?

Ultimately, nothing sticks to melamine. You can get some
(fake)adhesion from some glues, but there is no real 'adhesion through
penetration/absorption' IOW, a real bond isn't formed, but a seal to
stop the air from crawling into the joint, is.
If one were to find an adhesive that truly bonded to melamine, the
entire cabinet industry would beat a path to your door.

HEY! How do they get the melamine to stick to the substrate??? :~)

Not very well, as you have found out.
