Just connected Claude to my sandbox. I was logged into NetSuite and when I asked a question in Claude. It logs me out of the browser session. Is it not possible to use them in parallel?

When you were using Claude, were you logging into NetSuite with AI role you used to connect to it with?

Logged into browser as Admin Logged into Claude as the AI role 🙂

Try logging in as AI role in browser and use Claude/NetSuite. See if that kicks you out.
