5.1.3: multi monitor / multi plank dock setup no longer working.
Prerequisites
- [X] I have searched open and closed issues for duplicates.
Describe the bug
After updating to 5.1.3, when I boot or login, my primary display had changed and I have 2 docks on a single monitor.
I was able to restore the primary monitor, but am unable to get a second instance of plank running on my 2nd monitor.
I have my ~/.config/plank/dock1 folder linked to ~/.config/plank/dock2 and a settings file inside the dock2 folder with Monitor=1. I am unsure if I previously had a settings file inside the dock1 folder, but I do not at this time.
This setup was working without issue prior to the update to 5.1.3 and I had a duplicated dock on each of my monitors.
I have set sh -c plank & plank -n dock2 to run at boot time to active the dual docks.
To Reproduce
Steps to reproduce the behavior: I followed similar steps in this article for the setup that previously worked: https://heathpaddock.com/2014/08/25/dual-docks-in-elementary-os/
Expected behavior
Two plank instances created, with identical dock icons, one on each physical monitor.
Platform Information

Please check what applies:
- [ ] I'm using the latest version from git that I've manually compiled
- [X] I'm using the latest released stable version
Additional context
If there is a better solution to getting a duplicated dock running on each of monitors, I am open to it, it would be great if the OS had this functionality built-in.
As an update, I found a workaround, by going into the preferences of one of the docks, I was able to move it to the other monitor, and it seems to persist on logout/login now.

Can you explain how you did that? Wondering if you used dconf-editor and if so which keys. Thanks!
@akarasulu You can Ctrl+Right click on dock to open Plank Preferences.
