I own two iPads, and I use Shapr3d on both of them, not at the same time, but on the same day usually. Every time I open Shapr3D on a new one, it displays the error message, and I have to re-login.
What is the reasoning behind that behavior? Why can I use Shapr3D on Mac and iPad simultaneously, but not on two iPads? It is still just me, one person with the same AppleID.
Also, it seems that App store guidelines clearly state that if I own an app or a subscription, it should be available on all of my devices.
I propose to make these restrictions softer so that they will not irritate normal users.
