Slow to wake from sleep

I heard back from sandisk on the 5th Feb:

"We have been looking into this issue which you are experiencing.
SanDisk has been made aware of this issue and we are currently working on a solution for this. At this time however, we don’t have a fix yet. "

Its been 3 weeks and I’ve no more news. I am also suprised that for me this is such an easy issue to reproduce, so how come sandisk and frankly more people (eg ssd reviewers) didn’t spot and raise this issue sooner?

PS: Edited to ask: has anyone else raised a support ticket with Sandisk? I’m not sure they read these forums.
