Touchapp

These few days when users tried to access the company's intranet page via mobile browser, it will redirect them to /_layouts/15/touchapp.aspx?Mode=TeamSite&Page=ListOfApps&Path=?, which show a list of apps?? So user cannot access the intranet via their mobile browser.

Few days ago it is still normal and we haven't done any changes on the site. Any clue on how to fix that?
