I wasn't sure where to post this so I'll try here. I also wasn't able to locate where to report it to Mumsnet. I'm on my mobile phone so not sure if that makes a difference.
ISSUE: An Amazon advertisement is popping up on every thread I open. It covers over 3/4 of the screen and there's not an "X" to close it. If I wait it'll close in 10-15 seconds only to reappear 10-15 seconds later. Is anyone else having this issue? It's annoying and makes it unable to use the site.
