Hmmm, well that conflicts with the advice I was given by the very same a few years ago when I bought a flexwing
Also, (and this is just me pontificating without reference to licence or LASORs) if you look at the wording in your licence you can fly any single engine aircraft up to 5000kg. As there is no specific microlight rating and no reference to "microlight" in your licence, you must be able to legally fly on your CAA PPL A.

PPS. I can't even remember for sure if 5000kg is the correct limit
PPPS. At what age does Altzheimers start to creep in?
