Open as Layers In Photoshop Slow

I’ve reported this already in “Bug Reports” and my post was deleted with no resolution and no communication. I’ve reposted there and now looking for help here!

When “opening as layers in photoshop” the images are very slow to load in PS 27.8 vs. 27.7. This problem is confirmed by several other users I know. What used to take 11 seconds now takes 17 seconds. There’s a new behavior where each of the layers “flashes” up on screen for a split second before the loading actually starts and it takes significantly longer than it used. Downgrading to 27.7 restores correct (fast) functionality. 

Why would my bug report get deleted and if there’s a bug then, how are we supposed to report it so that Adobe will address it? Thanks
