Replacement Sky Max Hub, stuck slow green light

[SpaRhawKk]

Old sky max hub died. New one delivered. Updated in the MySky app, stuck on slow green light. Diagnostic via the app states hub connected but offline.. 'fix' connection and get error stating that function isn't working when checking my devices... how do I get the new replacement hub to work? What setting hidden somewhere isn't updating? Seems there is only advice on setting up a new upgrade to a sky max hub.. replacing one says to check set up in the app... it doesn't do that.. stuck in a loop.. any advice appreciated as the info from is shocking poor on what to do.

@SpaRhawKk assuming you have connected tge new hub correctly itshould complete its update but it can take a while to do so. If however it hasn't sorted itself call Sky as the new unit maybe faulty.

Nope. Spent another hour on the phone with them. The apparent engineer visit was a complete lie as it was passed to openreach who checked their systems and couldn't find an issue so closed the fault. No one told me they considered this 'fixed' yet nothing changed. I've 'another' engineer visit for today... apparently this time they are attending site. Being I was told that last time I'm not convinced. I've also had to purchase a WiFi dongle with data to be able to work from home. I can leave the house as the non existent engineer might turn up and they'll charge my £25 if I miss it... which I would as my Ring doorbell doesn't work..

Engineer visited. Promised to not leave until I was connected again. Will do all that's needed. 
2 hours later. He left. Back office 2nd line issue needing my build fixing. Would take 2 hours. All will be fixed remotely. Call sky if it doesn't...

Another 2 hours later and I got a text saying I now need ANOTHER site visit and the only available slots are NEXT WEEK!!!!

Another hour on the phone to Sky. Them saying it's Openreach and not Sky.. that they cannot escalate the issue (happening frequently) and they can't sort Openreach visits as it's a different company..  but.. Openreach have 48 hours to fix it!!! Erm.. it went down 05:45 Monday morning.. 

so, anyone seeing a green light on the box and 3 lights on the ONT, know you're in trouble.  You're in for a real runaround. Buckle up.
