Norton wifi security vpn won't turn off

prior to an update of Norton wifi on my ipad mini I was able to turn VPN off in settings easily when at home.  Now the switch flips back to the on position immediately after sliding it off.  It has no trouble connecting to WashDC vpn site, but having the vpn active may be interfering with some operations relying on being on same local wifi, e.g. photosync, chromecast.  It has to be able to be turned off and then on when out of country to be useful.  After writing this much, I went looking to delete the app and when I opened it off the desktop I was able to successfully toggle it off.  ERGO I think the settings switch is buggy.  (I did power the ipad off and on without clearing the problem and checked app store for updates).
