My problems, yesterday at least, were on a moto g5 android mobile, a samsung s10 and a samsung tab A tablet. No ad blockers etc. In fact one of my friends signed up for a free account and connected immediately. This is a problem with the sign up process.
This morning I am still unable to send email either via tablet or laptop. I receive email but I get either a 'connection refused or ‘cannot contact outgoing server’ error. Both emails have been working perfectly for a week or two. Now this. It doesn’t fill me with confidence.
Now to navigate the support with Pure which has been an experience on its own.
