I replaced Superhub2 with VM Hub3 , four days ago, and have now, my two iPads, iPhone, and two Apple Homepods all connected to the Hub3. Both my iPads and my iPhone are now using 11.4.1 - so far with no problems at all. In addition, I have a MacBook Pro connected wirelessly to the Hub 3.
I think that the range of the Hub3 wifi is marginally ( a few feet ) better than the Superhub 2.
Oh, I also have four Ring wireless doorbell, camera and alert ringers all using the same Hub3 wireless network.
So, maybe , I’m a satisfied customer ( apart from the Virgin notification of a price increase , which Is not owing to my Hub 3 upgrade ).
I hope that helps.
