It is not you (or your devices). It is eBay app issue. Many people are
reporting the same issue
herehttp://community.ebay.com/t5/Technical-Issues/Freaking-eBay-App-LOADING-glitches/m-p/27551081
The good news is that you are not alone. See this thread
http://community.ebay.com/t5/Technical-Issues/Freaking-eBay-App-LOADING-glitches/m-p/27551081The
bad news is that nobody has come up with a solution. Still silence from
eBay
I also face the dreaded nsposixerrordomain 100 error when using the eBay
on my iPhone. Other apps works with no issue. Has anyone heard back from
eBay?
