How to roll back app version?

Is there anyway to go back to the previous smartthings app on iOS, this latest version 2.0.6 is just plain awful. Between being logged out randomly which is a huge deal by itself, but also the dashboard is constantly showing things incorrectly in regards to doors being open, presence incorrectly displayed, etc. even though the device page is showing things correctly, the dashboard is wrong.

I’d love to go back to the previous app version and have things actually work over the holidays.

if you have a backup of it in iTunes then yes you can restore back.
