Sounds to me like the sealant you've used is acrylic or partly acrylic
rather than silicone. You need to use "sanitary grade silicone", you
will recognise it because it's the most expensive stuff on the rack! It
is very flexible and should take up a lot of movement. Stinks of vinegar
while curing.

failing that - order from screwfix and it is usually cheaper than the
naff acrylic offerings from the sheds!
