tiling onto plasterboard held up by dry foam adhesive

[arbitrary]

Any issues tiling onto plasterboard held up by dry foam adhesive onto a breeze block wall as opposed to using dot and dab; in other words is the dry foam adhesive strong enough?

And any advice on how to deal with walls that aren't quite vertical/level if using the dry foam adhesive? This was reasonably straightforward when using D&D by varying the size/thickness of the blobs but the dry foam adhesive instructions make no mention of this - they must assume all walls are perfectly flat and square!

It for the walls of a shower room - the shower niche itself will be boarded with aquapanel or marmox or the like.

It should be no diffent to wall adheshive fixed ones, so;
The maximum weight of tiling which can be supported by a dry, well-adhered plaster background is 20kg/m2, generally equivalent to ceramic tiles with a thickness of 8mm or natural stone tiles with a thickness of 7mm.When fixing directly to unskimmed paper-faced plasterboard surfaces the maximum permissible weight is increased to 32 kg/m2. These weights include adhesive and grout.
