Recently started using the Linux Player on Ubuntu 18.04, everything was working well, so I started playing around with a secondary snap instance using
sudo snap set system experimental.parallel-instances=true and installed with
sudo snap install xibo-player_2.
This worked fine, and I can run either instance separately, but I cannot run both side by side because AppArmor freaks out.

I haven’t yet figured out how to switch AppArmor to complain mode for a Snap, but once I do, I will troubleshoot further.
Anyone play around with this yet?
