Ive been having connection problems using instagram with your service? Instagram works fine with other internet providers when im at someone elses house but as soon as im connected to virgin (at my house) nothing will load on instagram, ive had people come to my house and say the same thing, it also happens for the rest of my family
I understand your problem can your please login into your account at https://my.virginmedia.com/home/signIn once logged in goto "My Apps" top center and then choose "Web Safe" once there make sure that "Child Safe" is turned off as that will block by default all Social Media.
I dont work for VirginMedia all opinions are my own. 39 years in IT.
