OK. I thought the manual download was for those who couldn't wait for the system rollout. I saw this from the "community" thread...Think it was posted in the 1st release notes that this will be a manual download only release.
Since I've not read anything good of this release, I'm content to hang w/6.2.1 for now.This release is staggered. Automatic update notifications will occur throughout April/May for different regions at different times.
