The company's attempt to address concerns about compulsive use is its time-management tool, which sets a default limit of 60 minutes a day for app use. However, internal documents reveal that this tool is ineffective, with teens still spending an average of 107 minutes on the app even when it's switched on. The company's own research found that minors lack the executive function to control their screen time, making it difficult for them to stick to the recommended limits.
