I have Lync 2013 installed on my Nokia 925. When signing in for the first time it asks me for my mobile number however the number is not saved when I close out of the app. When going to the settings menu the mobile number field is empty. I've tried re-entering it within the settings menu. But again, when I close out of the app, the mobile number is not saved. This has occured for all releases of 2013 for me. I do not have this issue for the Lync 2010 mobile app for Windows 8. Has anyone else experienced or solved this issue?
Installed Version: 5.3.1037.0
Phone: Nokia 925
