Yep, I read that before I posted.
Having said that, the tracks endpoint was working beautifully for the past ~3 months since I've been using. Because the endpoint is live and not down, I wanted to let you know about this issue as it may be less prone to automatic detection, and also to notify other users who may be using it so that they can work out an alternative for their apps.
No ETA expected and no request for it fixed, just a heads up mate.
