Is anyone else having issues with the tab  S6 Spen where it draws without the nib actually touching the screen? It's making it pretty unusable and the main reason for purchasing this tablet was for the Spen and ability to fill out and sign documents without the need of printing. I've tried changing the nib in the pen and nothing fixes it the closest fix I've found is pressing on the nib really hard but that only fixes it for a minute at most.
