I bought the TCLNXTPAPER14 and have put 89 piano pieces on MobileSheets and have organized set lists.  I have a PageFlip and can bluetooth page turning.  I play piano gratis at nursing homes/memory care units, homeless centers, senior centers and anywhere they will let me. I have not been able to figure out how to  activate or use the T pen (Stylus).  I try to write with it and nothing happens.  I have it attached to the magnetic side of the tablet.  I press the button and the blue light goes on, but I can't get the thing to write.  Instructions that came with the tablet haven't helped me.  TCL support hasn't been much help either. Do I have to activate it to the tablet then somehow connect it to MobileSheets?  As I am older, technology has been difficult for me. In fact I am not sure how this forum thingy works.  Is there anyone out there that has a TCLNXTPAPER 14 that can tell me how to use that T pen?
