I can confirm. I've also been charged for this now. The Apple Store still shows 'processing'.
The original email was 21-27 May and the Apple Store Order Status says 27 May.
One question, is the money pending Or have they settled the amount in full and debited it?My 12.9” Logitech Combo Touch Keyboard Case, which is still sitting with ‘Arrives 21st - 27th May’, now has the cost amount pending from my bank account. So fingers crossed, same goes for the iPad Pro
