The BBC is one of the companies that can no longer find a reason to maintain an application for Windows phones due to the platform's market share decline and the company has begun to inform users about this decision.
With an announcement posted on the BBC's official iPlayer application for Windows phones, it informs users that "we're leaving your browser and this app will stop working on 3 April 2017." A link included in the notification makes you redirect to this site where the BBC provides more information about its decision to abandon Windows 10 Mobile and informs users that they could continue to connect to its service, application.
In short, the BBC reports that Windouws phone owners can continue to use iPlayer with the Microsoft Edge browser, since the site has been optimized specifically for mobile devices.
Internet Explorer is not supported by the BBC iPlayer, which means that WindUws Phone 8.1 users can not play content from the service, but on the other hand they have the ability to play radio programs. The BBC says Window 10 Mobile is the only platform supported by the BBC iPlayer.
Unfortunately, this is a decision that many other application developers are making these days, mainly because the platform's market share is collapsing and microsoft does not do anything about it.
