 + Works with any service that accepts challenges from Android devices on the same endpoint.
 + Incompatible services:
   + Netflix (unless a browser/PC device is provided, which is rare)
+  + VdoCipher (ditto)
 + Some services may detect your browser and interfere with PlayReady playback. Try using a user-agent changer extension, or use a Chromium-based browser for PlayReady playback.
 + Firefox-based browsers may fail to play some PlayReady-protected video, with an internal error saying `ChromiumCDMParent::RecvDecodeFailed with status decode error`. This is a problem with the browser's ClearKey handler, and Vineless can do nothing about it. Please use a Chromium-based browser if this error occurs.
