Exactly the same thing here: followed the official upgrade process on May 12, everything appeared to succeed (saved a screenshot just in case), but the resulting address has not received the 6000xlm even many weeks later.
I posted on Reddit but the post was removed, and my email to the support address has not been replied to. I know at least one person had their funds stolen by a fraudulent upgrade intermediary, but their symptoms were different - my newly-created address shows up as not yet active, afaict. I would think that the upgrade payment itself would activate the address, without needing an additional 1xlm deposit.
In any case, I'm frustrated by the radio silence, and the whole thing feels shady.
