Be Forewarned

I accidentally hit the "Try our new photo experience beta" - I had done it before and just opted out. Saturday the blue "Opt-out & feedback" would not let me out , I could add no title or description, select sets or groups or add tags. I worked with Yahoo Help Center - they said the opt-out has be disabled. To get to this point I have to delete all cookie and clear the cache and restart the internet. If I close flickr I have to redo the entire procedure.
