Mudi V2 Youtube Restriction

App is universal for all models. It is normal. On E750 no parental control installed.

Gl.iNet removed it as it takes too much storage. If you have SD card plugged in install following:

gl-sdk4-ui-nasview
shadow-useradd
samba4-server
samba4-utils
kmod-usb-storage-uas

But do NOT run it without extroot (manual) as you can run system out of memory.

I don’t think you can add it. If you need to block something specific, add it to hosts as:

0.0.0.0 domain.com

If something more serious needed use BanIP with list what you want.

It can be browser problem, try incognito mode. Also enable encrypted DNS (rarely default DNS can do that if ISP set restrictions (usually by your request)). Guide (link)

P.S: You can use NextDNS to achieve parental control mostly
