Hi Barb,
Maybe you could pass this through to your contact if you see fit.
As some background I'm suffering from overnight battery drain from a fully charged unit as well as the keyboard issue. Both instigated at the same creators update.
After a full charge then leaving the surface shut down for 3-4 days (which fully drains the battery as it wont switch on without a power supply)... If I attach my type cover it works and functions fully I can even put the unit to sleep and wake up without any issues. If I restart or shut down however the keyboard functionality is lost again.
I've replicated this behavior several times now
Thanks
Neil
