Reauthorizing device issues

I’ve noticed that when I use too many devices (I have Shapr3D on my Macbook Pro, iPad Pro, home PC and work PC) instead of removing the license from the device used the least, it seems like it is removing the license from the device I use the most. I am typically bouncing back and forth between iPad, home PC and work PC, but it never takes the license from the Macbook, which is used the least, and always removes it from the iPad, which is used the most.

Also, when logging back in on the iPad, why can’t it remember that I am using the Apple Pencil? It asks me every time.
