Hi,
I am having exactly the same issue with the adaptive keyboard going off
after suspend/resume and would be happy to help debugging the issue
(within my limited time). Please let me know what I can do.
One thing I noticed is that on (at least the first) resume the keyboard
goes on for a very brief time and then switches itself off.
Best,
Philipp
P.S.: I am not subscribed to the list.
