Win10 Mobile Preview 10586.36 may be a cumulative update to be pushed

On December 5th, Microsoft began to push a new version of Win10 Mobile Build 10586.29 to Insider users. The upgrade interface has been exposed last night. Insider Fast Track users can now open their phone to check for updates.
And this morning the Script House home has just reported that Microsoft is preparing a new Win10 Mobile preview update that will fix the 10586.29 issue. There is now evidence that Microsoft is testing the latest Win10 Mobile Preview 10586.36 internally, which may be the cumulative update for the upcoming Win10 Mobile release.

Win10 Mobile Build 10586.36 is still part of the Win10 TH2 branch, after the Script House reported that Microsoft is already testing the Win10 RS1 branch, including the latest 10.0.11084 and 10.0.11085. Today Microsoft has pushed the Windows 10 PC version of RedStone major update to the first preview version of 11082, but it is not clear when Microsoft will push the first Windows 10 Mobile RedStone version.
