Six months have now passed since I first reported this problem to the EBC. Still it has not been fixed. EPO is missing from the Web-based ADS function in Patentcenter!
EPO is in the web-based ADS function in EFS-Web. But it is missing in the corresponding function in Patentcenter. This is bug report CP9 and you can read about it here.
This would be so very easy to fix. It would be a matter of adding one line of text in a list item on a web page.
