the OPUS player will be available everywhere on Monday, 4th June. While we promised that the OPUS platform would be released in May 2018, our main priority is to deliver a working product with as few bugs and errors as possible. To avoid the finished product from looking rushed, we find it necessary, unfortunately, to delay the release slightly to the beginning of June.
Sorry for any inconvenience this has caused, but hopefully in the long run, this small setback of a few days will not impact the OPUS project in any significant way.
The platform will be available on web, Android, and iOS.
