Hi Drew, email address is jharaty@adventureluxurytravel. I also had the same issue as not seeing the upgrade and doing it twice even though I had been charged last week for it. Second time I signed up for it again, it went through and showed me at 5GB. I have logged out and back in multiple times today and still the only email showing the email I am getting to this email address after upgrading to the 5GB. Thanks.
The emails disappeared today. The 5GB size upgrade did not appear until I changed the size again today. It then showed 5GB storage and all my previous emails were gone. Thank you for getting them restored, whenever that happens. I will let you know.
