PS4 friend's list problem

Whenever I log in to Overwatch and try to join/create a group with my friends, it glitches and says my friends list is empty, and won’t allow me to join any group invites unless I restart the whole application.
This used to only happen occasionally, but now it happens every time I log in after the app has gone idle.

I usually just put my PS4 to sleep rather than shut it down entirely when I’m not using it in case any apps need to update in the background. Has anyone else been having this problem and is there a way to fix it other than just closing the app when I’m not using it?
