I am on an older iPhone, but I don't think that is the issue, it's an iPhone 8 but I have this problem with the Mail app, only when on 4G.
I can get on Safari no issues when out and about and it loads fine, but 'Mail' will not update messages, and comes up with the error message updated ‘2020' when checking for new mail! Was out for 3 hours yesterday and was turning phone on and off, and airplane mode on and off and it makes no difference. Problem being, my email provider blames my mobile carrier, and you've guessed it, my mobile carrier blames the email provider servers, so I am in a position of it never being resolved. This has happened for several months and have resigned myself to not being able to check emails when out. All settings are correct and have worked for years
When phone is on WiFi it’s fine, no issues, so I wondered if this problem has ever happened to anyone else ever?
