Norton Identity Safe will not stay enabled in Chrome

Since Norton Toolbar update 2015.5.4.11 earlier this month, my Norton Identity Safe will not stay enabled in Chrome (v. 46.0.2490.80 m). Each time I open Chrome, and sometimes while in use, I must go to Settings->Extensions and enable Identity Safe again!  This is a major time-wasting inconvenience. I tried uninstalling Chrome and installing the newest version but that had no effect. I saw no way to reinstall Identity Safe without uninstalling all of Norton Internet Security. 

Does anyone have an answer?
