For a while now I have issues sending mail when on my home wifi, 9 times out of 10 when i try to send the email it just sits in the outbox but if it turn off wifi & go onto 4G it sends straight away. I get a warning saying the password or username is incorrect, ive checked its correct & tried deleting the mail account & re adding it.
There is no issues receiving mail on wifi or 4G. Occasionally on wifi it will send ok.
I was like this on ios 13, i was hoping ios 14 would solve it but still the same.
Im using the apple mail app & i have an email. VM is my internet provider.
Any ideas?
