Wildolo device not connecting?

I have a feeling these kinds of posts are common, but I couldn’t find anything for this specific brand.
I bought a toy off the list (y’know, the ones that show which ones are compatible with buttplug.io?) and it arrived earlier today. Once it was charged, I attempt to connect it to my PC, hoping to play some Ultrakill.
The toy showed up in the Bluetooth list. Wouldn’t connect. Okay, maybe it’s my computer, might as well try it on my phone.
Shows up on my phone’s Bluetooth list. Doesn’t connect there either.
HOWEVER! It works just fine with the mobile app.
I literally dropped fifty bucks on this thing for Ultrakill please help me out.
Wildolo seems to be a rather niche brand, and frankly, a little sketchy.
