[Help Please] Huion GT-220 V2 (2048) Pen Pressure Not Working in Photoshop

I just picked up a used Huion GT-220 V2 (2048) with the P68 battery pen, and I have it connected to my M1 Macbook running Mac OS Big Sur. The pen pressure sensitivity works fine on the driver, and in Affinity Photo. However, Photoshop keeps showing a triangle next to the brush settings saying that pen pressure is only support with pressure sensitive devices.

Is this a compatibility issue due to Photoshop being too picky about the devices being used, or is this a known problem with an easy remedy?

Thank you!
