Simplisafe iPhone app always restart when switching between apps

Even with the latest Simplisafe iPhone App version 2078.51.0, when switching, e.g., out of the Simplisafe App to the iMessage App and back will cause the app to restart.

This annoying "restart on every entry" feature is very bad on useability, especially during the set up of 2-factor authentication. If we missed the banner notification from the iMessage for the authentication code, we have to switch to the iMessage app to read the code, then switch back to the Simplisafe app to enter it. But when switched back to the Simplisafe app, it restarts and forced us to restart the process again! Why can't it just continue from where it was left off to allow us to finish the process?

This is really useless and making the 2-factor authentication very challenging! Please fix this annoying "feature"!
