I tried that one and firstname.lastname@example.org (the one associated with my phone apps). Also, I am of course on your website that is synchronized to my phone. Also, this has worked FINE until recent update, as per usual.
I just made a purchase on ebay yesterday. An old purchase that was delivered last week (!) just showed up.
So, NO ebay sync, no notsification of deliveries, and no updating!!! All since update app. 2 weeks ago.
I AM NOT doing anything differently than I have been for the past few months!
