I have two house with one instance running in each house. When I want to connect in one instance, I need to logout, write the url of the other one and connect me.
It could be great to have instead a simple Log Out button in the settings a button (or directly a drop down) to switch accounts.
You can already be logged into multiple instances simultaneously as well as easily switch between them with a three-finger swipe.
Settings - Companion App - Add Server
In addition to the above, and outside of the mobile app, you can even tie your two instances together using the Remote Home Assistant custom component so you don’t even have to switch to the other location.
