Most likely, because I would guess that >90% of my up to date (after middle school) use of maps was highly localised to plaxe of interest.
Which doesn’t really show projection type (or brings relevance of it to surface).

I don’t get it,
from my memory of geography class in 5th to 8th grade, in elementary, we extensively learned about all kinds of maps, and projections, so teaching kids 3-4 is huge downgrade.

plus, app is poorly translated, half baked pile of garbaage that some time just didn’t work

so Your one week could easly turn in to 3, or if You’re unlucky, like me - 6 weeks
