Hey Saar, thanks for your post!
Unfortuantely we can’t roll back the version to support older iOS. As we further develop the platform this year it will be important to always have the latest version of iOS so that we can continue to improve the app with the latest available features and functionality.
Later this year we will integrate Apple Health and wearables all of which will require the latest update of iOS.
Sorry we couldn’t help on this occasion
