Hi Richard and Welcome. My Name is XXXXX XXXXX I look forward to assisting you today with your question.
We can try to change the store in different way. On your iPad, goto this website : http://appstoreswitch.com/Tap Ireland option from that website and that will allow you to switch the store back to Ireland. Please let me know if that didn't work, so we can continue troubleshooting.Best Regards,Ashik
