I’ve had the same issues with delayed messages/notifications in the past and every now and again I experience some kind of minor hiccup or glitch which can last anywhere from a few hours to days.
From what I’ve heard Medium are constantly working on their platform and app services, updating and trying to improve things for the better (I hope) so I guess this is when we experience the issues.
As this is still a relatively new platform, in the grand scheme of things, I think there will continue to be minor inconveniences for awhile until they find a model that they are completely happy with.
Until then, I hope support resolve some of your issues and answer your questions which will allow you to create and publish more great articles keeping us all in the loop 😊👍.
Thanks.
