I've had the same issues with my instagram app. I'm with ID and my phone wasn't loading instagram. My phone updated to include 'WIFI Calling' at all times. I've turned it off and instagram seems to be loading fine now.
I have also got this issue with virgin! I thought it was our WiFi connection (newly installed) but looks like a lot of people have this issue: what a joke that nothing has been done yet? I keep switching to 4G and the app works fine but it’s meant that I’ve had an extra data bill as I’ve been running out of data.
i don’t really appreciate or understand why I should pay over £100 for tv and broadband for something so simple to not work? I wonder if I would have this issue with sky.
I've tried everything - happen to know a few people at Facebook who have also done a little (very little, mind you!) digging for me. They see me connecting from my home IP across their network (Facebook, WhatsApp and Instagram) so the connection to them isn't the issue, it's something Virgin's doing with the routing or attempted caching of the sites to speed access up though caching or some CDN on their network. Isn't the ISP's job to do that, is down to the service itself to offer these - Facebook has various PoPs across the UK so again, no reason for Virgin's network to fail to connect over the app.
Why has no one from Virgin even commented on this thread yet?
My home setup does not use the built-in wifi, that's off as Routers were never designed (and still aren't) to handle all the tasks ISPs assign them - we have a pro-wireless setup in the house; UPnP is on for testing now but it would make sense for Virgin to just confirm what their issue is.
We have exactly the same on our virgin media router. When loading Instagram the app doesn’t work at all, really slow to download or upload. Everything else works like Facebook, Pinterest, Amazon and netflix. Drop WiFi and Instagram loads instantly.
