Problem with cdn.districtm.io
All of a sudden on my iPad on Safari, when I go to certain website — usually news or newspaper sites — the page disappears and instead something called cdn.districtm.io pops up, asking me to open it with an application. It appears to be something related to Amazon. I tried deleting all cookies in Safari, which seemed to help for a while. But then it came back again.
iPad, iOS 11
