Since I updated to the new operating system my Nexus 7has been giving me issues. It's either WiFi or YouTube but unsure if my tablet is on for more than 24 hours and I go to YouTube to watch videos it won't play them. It gives a retry. I tried turning WiFi off and on. Doesn't work. Closing app and opening no. Restarting tablet does fix it. But it's a pain to keep doing that ever other day. Anyone have an idea what to do to fix this?
