What's Wrong?

If I start Claude code on Linux, I’m locked in on Linux and there is no option to switch

What Should Happen?

If I start Claude code on one platform them continue with another, I fully expect to be able to switch platforms on my phone. My interpretation is, one can monitor many Claude codes on my phone so I’m not constant going to my computer to click yes. It’s , and this either isn’t documented or is intentionally suppressed, that once one starts on a platform they are totally locked in; do not try to do anything in that session with another platform as it will fail spectacularly.

Error Messages/Logs

Steps to Reproduce
