In mobile, it is common to break complex processes into smaller simple steps. Users will move through several screens to perform a task that is too complex to be completed in a single screen. Despite the linear nature of those processes, we should provide users with a freedom of exploration. Users should be able to move back and forth to correct their mistakes or leave the process incomplete to return to it later. If the work done is costly, and leaving the funnel will make the users lose their created content, we must ensure that they understand the consequences of the action. If possible, it may be helpful to save a draft so that they can retrieve it later.
