Well, I’ve been using iPad 6th generation and a Nillkin stylus pretty well till the last Shapr3D update. I had a problem with the splines because I could not draw more than one curve with control points splines but that was all. Now I can see that the stylus is rejected because appears the message “apple pencil is not connected” in a red banner so I was thinking of buying one but you are telling me also that my iPad 6th generation is not valid, so there is no point so I wonder: normally, updates and upgrades are made to solve problems to a wider users base, not to create new ones or to reduce possibilities.
