Sorry to hear of your dilema with the cracking grout.
Unfortunately it may well be down to the substrate prep. as it should be braced sufficiently to provide a stiff, rigid and stable floor FYI;
1 Overlay should be minimum of 18mm screw fixed at max. 300 centres.
2 Fix tiles in at least an S1 adhesive such as Keraquick
3 Grout with a CG2 grout such as Ultracolor Plus (26 colours)
4 Perimeter Moovement Joint and at 6M centres fill with Mapesil AC same colour as grout.
best of luck with remedial works................................hope it goes well
