BP integrated Tilemap bugging on android

Hi i ran ino a problem while trying to make a game for mobile , i basically made a procedurally generated maze that constructs at run time , it works wonder on the editor but when using the ES2 mode to emulate a phone my blueprint class that has a Tilemap as a child it doesnt appear.
here is the blueprint in question :

here we can see how it renders normally on editor :

here with the ES2 emulation :

and here i just placed the tilemap manually before launching and we can see that it appears normally

So mobile devices cant handle Tilemaps spawned with blueprints ? Do someone knows a way to circumvent this ? thanks in advance !
