Probably lucky to have even gotten that far. I haven't been able to use Apple Music Preview at all, lol.
As far as I understand there doesn't seem to be an easy native way to. There used to be an electron app that got close, but that got converted into Cider, and Cider doesn't seem to allow high res music at the moment with the devs just saying they're working on it.
Most people have recommended side loading the android application on windows. With the Amazon App Store in the windows store bringing in "official" android emulation by Microsoft, you can do it through that now. https://beebom.com/how-install-apple-music-windows-11/
Can you not go to whoever you pay customs to in Canda to get a refund? Here in the UK I'm pretty sure you can claim back VAT/Customs charges you've paid to couriers when it first got delivered. Not the quickest route, though.
That said, I'm not a massive fan of Drop myself. I was one of the unfortunate people who bought into the Drop Panda, a product they dropped after like a year or something. Leaving most people with broken products. Fortunately mine did keep working, but they didn't deliver on any of their promises, like their app, nor was their aptx adaptive codec(which was originally meant to be low latency) ever useable from it.
