I watched the video about Mission Hub and read the manual but

I can’t figure out where Mission Hub saves my missions. I click save and then search my computer and the file is not there. Thanks for any help.

I think they are stored in the cloud.
You can download a mission and store it anywhere from the Missions Menu:


On Android devices the path is:
\Android\data\com.aryuthere.visionplus\files\missions__users\
