In order for current Insiders to update to the latest build is to roll back to Windows Phone 8.1, reinstall the Windows Insider app, and then update to build 10549. However, this isn’t the only issue, because the new build is releasing to the Fast ring, and Microsoft is also detailing a number of known issues that users have to be aware of before spending the time and upgrading to the latest version of the mobile operating system, which are listed below.
Windows 10 Mobile 10549 known issues
After the upgrade, you might be missing a few apps. If you experience this, the workaround is to reset your phone. After rebooting your phone, you won’t see notifications, such as new messages, until you unlock your phone for the first time. After that, you should see notifications for new messages just fine. This bug is fixed in a later build. You will be unable to make calls with Skype for Business, WhatsApp and other apps after upgrading to this build. The workaround is to uninstall and reinstall these apps from the Store.
While the software giant gets closer to release Windows 10 Mobile to the masses before the end of the year, we can still see some big issues that show the operating system still a work in progress. However, no everything is bad news, there are some new changes, improvements, and fixes on this build, and there still hope that every major problem will be resolved in time for the big launch.
