We've done a decent enough job on our patio but I have a couple of flags
i'm not happy with.

The flags are on a solid bed of mortar.

They need lifting on one side by just a few mm, i'm wondering if i'd be
better using some sort of adhesive/filler for this than adding a thin
wedge of extra mortar.

Opinions please.

Oh dear. You might not get them up easily. If you can, any old thing
will do I should think. Even earth as long as no stones in it. Sand?
They ain't going to escape the force of gravity....
