Hi
Thanks for flagging this, and sorry for the hassle of having to reconnect every half hour.
To answer your questions directly:
There is nothing your Claude admin needs to configure. No setting on that side will extend the session, so you are not missing a step in the setup.
The expiry itself is a current limitation on our side rather than something specific to your instance. We have already raised this internally and it is under review with the team for a change.
If you would like to track the progress, please raise a support ticket with us. Our support team can link your request to the development ticket and will notify you once it is implemented.
Thanks again for the detail in your report, it genuinely helps when we make the case for prioritising this.
