App automatically starts after screen time out

[rlridgeway]

While listening to podcasts my screen will time-out (but the podcast continues to play.) When I want to view the screen again, I will enter my pin but instead of seeing the home screen or the podcast app an other app Google Keep will automatically open on top of the home screen. I do not wish for Keep to do this.
Any help will be appreciated.
The device a LG 4 plus running Android 8.1.0

Go into settings and disable keep.

Thanks for the reply. I would like to be able to use Keep, I just do not want it opening automatically.
