SmushPro & Hummingbird

Hi,

I opened support access on my website and leave the following message 4 days ago and still no visit nor response and of course no solution…

«Hi,

HummingBird tells me to improve image compression and to that end to use SmushPro. SmushPro is active and reports that all images are optimized, HummingBird keeps asking… What shall I do ? Is it a bug in HummingBird or SmushPro ? I have the same problem on several of my sites. Hummingbird score suddenly dropped a few version back, but the images didn’t changed, so is it a new rule that Hummingbird knows but the SmushPro doesn’t ?»
