----sorry , this problem is coming with "keep notes " not mokee.
mi pad 4 plus, “keep notes” version 5.0.481.05.40
Mokee is nightly2018-12-17
When I was running the “keep notes” and pressed the exit button of system to exit keep notes.
Then pressed “recent task” button to open task switch UI, selected the “keep notes” , the “keep notes” crashed immediately and disappeared from recent task manual.
