For the last couple of months, I've been unable to send emails when connected to wifi networks. Doesn't matter if there is anything attached or if it's just a brief message - sending fails as long as I'm connected to wifi. As soon as I switch wifi off and revert to 4G, message sends fine. It's the same no matter what wifi network I'm joined to - home, work, friends'. Has anybody else encountered this and found a solution?
Thanks
