How to acquire Hanger Control?

[StrangerThings]

I saw inside my hanger, I can unlock more hanger slots by acquiring something called 'Hanger Control'. What & how can I get this?

1. You have to "earn" the Platinum Medal by completing 38 "Monthly Missions".
2. You have to have the Platinum Medal for 7 days before the 10th, 20th and 30th day of a month.
3. You must make sure to log in every day once at the Platinum status or you will "skip" a day.

I acquired the platinum medal yesterday, being 20th June tomorrow, does it mean it will unlock tomorrow?
Also, does it meant I can only use the extra slots on 10th, 20th & 30th? Or once it is unlocked on these days, it will stay unlocked for the rest of the month?

You have to have had the medal for 7 days to unlock that hangar, so you are not eligible for unlocking the middle month one on 11th-20th. Once you unlock it it remains unlocked for the rest of the month.

Correct, you will get "day 1" of the Premium login bonus chart and then on the 21st, it will reset to "Day 1" for the next 10 day cycle.

Remember, don't skip days.
