Probs with eBay uk app since Android update

I'm having problems with the ebay UK application on my Galaxy s2 since carrying out the latest Android  update 4.1.2 .I can search for items but when I tap on an item to view more details the item will not display I see the message ”We're sorry, the item can't be displayed and a blue "Retry" box . If I retry it then displays "sorry network lost".I had no problems before update. I have uninstalled updates...still the same. Installed the updates...still the same.My phone arrived with the ebay application already loaded and I am not able to uninstall /re install the application.Can someone please help cos it's driving me crazy. Thanks
