My son has a Nintendo 2DS, which is connected to the router. Any Youtube video played on the device starts ok, then stops after 10sec. This happens systematically when the device is in a group that has parental control ON even with all features (safe browsing, disabling numerical IPs) turned OFF. I put it on a group that has parental controls OFF, and it seemed to work at first, then it didn’t. The only way video playback can be restored is by turning off parental controls completely on the router. Any idea what could cause this, how to fix or to investigate?
