[SOLVED] Display sleep timeout is limited to 30 seconds

Hi Fairphoners, in the display settings, it’s possible to select a sleep timeout between 15 seconds and 30 minutes. However, setting it to anything above 30 seconds is ignored. Whatever timeout I select, the display will always fade black after 30 seconds. If I select a sleep timeout of 15 seconds, it will fade black after 15 seconds.
