Pool Tile Keeps Falling Off

[Sterling555]

I re- did the pool waterline tile myself and my tile will not stop falling off. I have read maybe its because I used grout/thin-set on the line in between the waterline tile and the concrete coping? Please help me!

Looks like he has ground movement with cracks in the deck or coping stones. Hard to say without seeing the whole area.
