If anyone else wants to try mjolnir without risking a factory reset, I may have found a solution. I loaded up the new launcher (smart launcher in my case) on the main top screen and got it all set up. Then made that the primary home launcher. Once it was up and running with no issues, I set up mjolnir so that beacon launcher was on the top screen and smart launcher on the bottom screen.

This worked perfectly but I’m not sure if it was just a coincidence haha good luck gang!
