BUG: Unable to log in with my Apple ID on Windows 10 Mobile

[ArturoGC06]

Describe the bug
When I click on log in with my Apple ID the log in page doesn't load and I can't log in.

To Reproduce
Open musi.sh on a Windows Phone device and try to log in.

Expected behavior
The apple log in page should load to be able to log in, or at least another method to log in, like log in using a token could work.

Screenshots

Smartphone (please complete the following information):

• Device: Microsoft Lumia 950 XL
• OS: Windows 10 Mobile 10.0.15254.603
• Browser: Onitor Browser (every browser in Windows 10 Mobile is based off the same Edge Legacy core, so it doesn't really matter, Onion Browser only changes the browser agent to bypass the browser incompatible warnings)
• Version: 0.9.6

Additional context
A feature to log in using a token will probably be easier than making the Apple log in website to load in this old browser. Curious enough, some websites use https://appleid.apple.com/auth/ to log in with an Apple account, which somehow loads fine on Windows 10 Mobile, but https://authorize.music.apple.com/ is what musi.sh uses to redirect to the log in website, and that page won't load. I hope you can manage to fix this, is my last hope to be able to listen to Apple Music on my Windows Phone device.
PD: the website itself seems to work fine if you use it without logging in.
