### Automatic configuration update

When the configuration of an Instance is being updated (for e.g. switching from no-MFA → internal-MFA), mobile client **does** **not** refresh the Instance configuration automatically if the **app is opened**.\
This is an intended behaviour.

If you want to manually update your Instance perform:

* **Manual pull-to-refresh** on the instance screen.
* **Restart of the application** (reopening the app)
