Huion WH1409 V2 air bubble
I just bought the tablet and the active surface has a big air bubble underneath. It moves up and down when I use the stylus on it. It is glued only on the edges and when I press really lightly it doesn't show any pen pressure applied, though on my HS64 it senses the same light pressure(and yes, I uninstalled the drivers and I restarted the computer before using the new one). Is this normal with this tablet or should I return it?
