A split along the tile edge specifically usually means adhesion failed on the tile side, so degrease the tile face harder than the bath lip next time.

Rub chalk along the door edge and close it. The rub marks show you exactly where it is catching rather than roughly, which stops you removing material from the wrong 30cm.
