KWong Monthly Channel (Targeted) gets feature updates of O365 more than once in a single month - max 2. Monthly gets only 1 update in next month. So, current Monthly Channel and targeted have build 1907 (July, 2019). So, Monthly (targeted) got this build in beginning of July itself, whereas Monthly got it at late July. Now, my current Insider build is having the build 1909 (September, 2019). So, in August, Monthly (targeted) will get 1908 before Monthly gets this update. However, my concern is that new Office Layout is not available in any Update Channel after following MSGuide's O365 activation (considering the fact that it was released for all O365 users, even ProPlus, last year in September).
