E mail on 5g Broadband

[Pie]

I have a strange issue on all of my connected devices, iPhone ipad & Mac. When connected to Three 5G broadband it downloads e mails, but when i click on one to read it, instead of the body of the e mail i get a spinning circle for a min or two before it finally loads up. When im connected via my mobile data, its instant?

im using Apples native e mail app 

Is it something in the settings?

Hi @Pie,

That's really odd, when you're connecting over mobile data is that also over Three, or a different provider?

Thanks,
Jonathan

No its with another supplier. It’s strange as it never used to happen

Hi @Pie,

Sorry for the delay in following up. I wonder if it's an issue with iCloud private relay interacting with our network? If you go to your iCloud settings and disable private relay is it still the same?

Thanks,
Jonathan
