So... Due to me being kinda confused understanding all of these Google Analytics features, and think it's kinda using a lot of work to check one by one of each property... I ended up trying Google Data Studio, and Voila!, it's here. Now I could check each Google Analytics data with some dashboard only. No need to worry about the error that often happen with Google Analytics, no need to check each anymore, and more benefits. I hope I could see more way to utilise this in the future though...
