Currently, it is unfortunately not possible to cast via Chromecast to Prowise screens. Users may notice that the screens are not visible in the Chromecast list or see a message stating that casting is only available from specific video websites.
We have found a solution to the problem and are currently testing it internally. If all tests go well, we expect to provide the solution via an OTA update.
We apologize for the inconvenience and thank you for your understanding.
