Unable to download songs even though they appear unlocked.
Both "Single Track" or "All" on all characters show "Downloading (0%)" then "Download Failed" after about half a second.
Cytus II 5.0.7 on Jailed 17.4.1 iPhone SE 3rd Gen (custom bundle ID and app name)
Unfortunately Cytus does not seem to use system certificates for song downloads as I can capture the https-encrypted announcement images' request and view them but attempting to capture song downloads results in an ssl error. Capturing the request without ssl proxying allows the request to complete, with an oddly high response size (5.21kb, identical regardless of which song requested) but still 200 response code.
I hope my initial attempt to solve helps you.
