I Tiled this 2 Year Old Shower and It FAILED! Find out WHY

This is a follow up to a video I did where we tried to do a repair on a subway tile shower that was cracking on 2 of the 3 walls. We initially thought we could just repair the cracked tiles, but as we tried to remove the tiles, the cracking got worse and it ended up being too much work to try to repair.
In this video I describe what went wrong-- a combination of a one coat float (TCNA method B4441-14) with Aquabar paper behind it as the required cleavage membrane, and a soft bisque ceramic subway tile. Also, when I tore it out, I noticed that water had seeped under the Schluter kerdi drain into the mortar bed below.
We are re-building this shower at our cost, and are going to use all of our experience and resources to build the best shower possible for our clients.
