Safari and chrome user. Your web clipper pop-up LITERALLY had me go from Premium user straight to uninstalling and never using the extension again. But because the web clipper is the primary way in which I use Evernote, it looks like you lost a customer completely. I deal with PDF's on the web at least 100 times a day between work and school and having to close that pop-up every time is absolutely ridiculous. And by the look of this thread, Evernote has done nothing to fix it for over a year and a half.
Allow me to help: REMOVE THE POP-UP FROM THE APP ENTIRELY.
I should be free to clear my cache whenever I see fit. "Not clearing my cache" is not a solution to this problem. YOU removing the pop-up IS.
