Just received a reply to my email rant to eBay yesterday about the all too frequent technical problems lately. Now they don't even acknowledge that there was a problem. 
Hi ,
Thanks for contacting eBay in regard to the issues in the site.
we apologise for the inconvenience this has caused you. We are fully aware of the error and have worked with our technical team. This issue is now resolved. If you still have buyers who can’t go through with the checkout, please provide to us the buyer’s user ID so we can assist them.
In regard to printing the postage label, we haven’t received any reports regarding this. You can provide to us more details like the item number, error message and any helpful information so we can escalate it to our Technical team. Your patience is highly appreciated.
We value your business on eBay. Have a good day, !
