First thing I would ask is is this a suspended wooden floor and how heavy are the tiles. It is quite easy to exceed the rated loading of the joists underneath if it is.
Most fllors take thimgs like pianos and even water tanks and baths wich are a lot heavier than slate of 5mm thickness etc.
Flooring slate is not that heavy, but any flexing will break the bond and lead to lifting tiles.
I have used Ardurit flaxible tile adhesive over chip flooring. It has a little give.
Effect is very nice.
Not in older houses. Putting a new bathroom in upstairs with complete disregard for joist loadings is far too commonplace.
