iPhone Whatsapp issue. Can't see images or videos on mobile data.

[sswats]

Having a very unusual issue that's been going on for a few months.

On 4G (EE) video and photo messages don't open. I receive the notification, the blurred image is there but doesn't download. But on WiFi no issues.
I've been checking online for a solution usually reset network settings, or check whatsapp is able to use mobile data and both are enabled. Did a full reset and reinstalled whatsapp all with same result.

I have taken to both EE and Apple and both say the phone and the signal is fine (although did send a new SIM with same issues).

So any ideas what steps to take next?

Have you got any example screenshots?

Edit any personal information out.

My father in law has had this on his iPhone 6 for a while now and I am due to look into it during the easter hols as he lives up north from me.
The last time I had researched this problem as it is a common issue I sent him this link below. Perhaps give that a go?

Try installing and enabling the 1.1.1.1 app and see if that makes a difference. It forces the phone to use the 1.1.1.1 DNS servers no matter what connection you are on.
