Leviathan v2 spacial Audio not working in Synapse 4?

I purchased a Razer Leviathan v2 recently, and I’ve noticed that Synapse 4 doesn’t have any effect when I try and change EQ or spacial audio settings. I downloaded the THX spacial audio app, which does work when I try and change settings, but it’s asking me to pay $30 to unlock the app after the trial. I tried to purchase the app through the store, made the payment, and saw the success page but then received an email saying that my order was cancelled and I should contact customer support, which I already did. I had a 5 minute chat with an AI assistant which was less than helpful. Anyone got ideas? Everything says I should be able to use Synapse 4 to EQ and calibrate THX, but no dice there, and I can’t use the special audio app until I find a way to purchase it. Thanks!
