Why is that? I can only imagine 2 reasons. They fear that too may downloads will crash their servers, or they fear software bugs and want to limit damage to a few guinea pigs?
Yes you can only imagine.
No different than OS updates for computers and phones. Apple updates take a few days for WORLDWIDE update migration. Android is a week. So what?
Guinea pigs? Absurd. Don't upgrade!
You're moaning it takes too long while “suggesting” those that do so when first available are guinea pigs.
The absurd is the last refuge of a pundit without an argument.
Or a posting agenda to aid the OP. 😰
