You have not yet purchased any apps.
Well, the app store this morning is not showing any of my purchases (from any computer) and I need to reinstall one of them immediately to continue working.
Called support andthey wanted to make me pay for a support fee.
Was asked how many appso I purchased (not something I keep in my head so I gave my best guess)
Complained about paying a fee for something Apple is responsible for.
Put on hold to await feedback from senior advisor.
Was told to go to https://expresslane.apple.com/ to fix issue.
Got automated reply saying I'll get a response within 24 hours (and I need the app now)
I miss my personal installers.
Still waiting....
Hope this helps.
