kamvas pro 13 pen isn't working right
i got the tablet about 4 months ago, my pen just isnt working right since about two weeks ago (i contacted the help desk then, but responses have been very slow and i need a solution asap), ive tried multiple things like reinstalling the driver a few times, trying to check if it works properly without the driver, i even checked if my old wacom pen would respond to the screen because i was so desperate, and altho i'm not able to draw with it (obviously), it did follow the pen smoothly, in contrast to the huion pen.
the problem is that it glitches, sometimes doesn't respond at all, or lags when i'm trying to draw. (i attached a video)
i dont remember dropping the pen (i made it a habit to put the pen back in the holder every time), it just suddenly happened one day.
