I've tried a couple of times in the past and again today without success.
It was for t-shirts in Tesco, and no matter how I tried to submit it, all I see a quick "oops" followed by an error message.
I've tried to ensure no special characters such as a "-" were used, but nothing seems to work. I even switched off WiFi in case it was an issue with Tesco's free wi-fi. I took a photo and even went through the cropping options in case it was an issue with the file size.
The only thing I hadn't tried was adding a "£" in the price field.
What am I doing wrong ?
