Since the ads showed up (or before?). I can't read the messages in my inbox or sent folders. It's like they've been shut off with an opaque screen covering the first couple quasi visible sentences. Has anyone else experienced this?
Try hitting F12 then the settings icon at the top right (looks like a little gear) scroll down and click the box to disable Java Script. Refresh the page and then Hit F12 again. This works to get past most paywalls and many overlaid ads in my experience.
