Windows Insiders running the latest builds of Windows 10 Mobile had some issues with the Voice Recorder app. A lot of Insiders reported that the Call Recording feature wasn’t working consistently on the latest Insider builds of Windows 10. Today, Microsoft released a new update to the Voice Recorder app for Windows Insiders which apparently fixed the issue.
