yup seems like started very recently, annoying as hell

There is a deselect button on the bottom right for me.. using android btw..

mobile version has the "All" check box at the bottom left which you can untick to unselect everything in cart as well
mine always work without fail, I wonder why so many grey out among users here
perhaps shopee knew you guys are rich, so can checkout everything in cart 

probably, unsupported old operating system is vulnerable to hacks etc

I think that selected all item grey out started recently..
B4 this its working fine, can just untick select all..
I think not android version related, mine latest android also have this problem

my handphone android 5, can click to unselect all

have also sent email to shopee as well,

annoying as hell.

This is the email reply from shopee regarding the cart auto select all thing.

The odd thing is it never happen before maybe months ago,why now?

The apps developer was lazy with this i guess?

If it is not broken don't fix it.
