Here’s the Winter Flowering Jasmine in our garden. We cut it right back in October.
I too have Winter Jasmine which is flowering well. But I would be very interested to know how far back you cut yours, please. Mine is about 6' high /wide. Did you cut yours down low? I give mine a good trim, but perhaps it would benefit from a more severe cut? 
Our winter flowering jasmine has suddenly started flowering, sorry, no photo as it would mean walking across an extremely soggy lawn!
However, we were surprised because it looked half-dead not long ago, another casualty of the hot summer we thought.
It wasn't cut back because a blackbird was nesting in there.
Now it's green again and flowering really well.
