Well,
I see this all to often when the substrate is not prepared properly, you certainly have adopted an issue. There is no real solution except to tear it up, add another layer of plywood but, you may have elevation issues at the doors, removal of baseboard, shaving of doors and an eagle eyed client who is hating every minute of it as his wife is ripping him from a far.
Anti Fracture membrane has it's limitations as well, it looks like a fairly large tile in the photos 12"x24" or 16"x24" the previous post is correct the tile is next on the list for failure. If there is a lot of flex as you have stated BC in the floor there is not a lot to do here or easy solutions.
Contact Mapei they as long as you follow the wriiten specifications they provide and use their products, they will warranty the install for ya, I am pretty sure Laticrete will do the same.
But, Like anything else in life no foundation...... no future.
