Here Maps announced it's dropping much of its support for Windows Phone and Windows 10 Mobile, Engadget reports.

The company is pulling its apps from Windows 10's app store on March 29, and a workaround that kept its apps running will stop working after June 30. The Here apps for Windows Phone 8 and Windows 8 will continue to work, but you won't get more than "critical bug fixes" from now on.

Here says that it didn't have much of a choice. If it wanted to continue supporting Windows 10 without that workaround, it had to rewrite its apps "from the ground up."
