I have Gmail enabled with the send button "Send and Archive", but when I reply to an email, the message still stays in my Inbox.
I'm thinking that it could be one of my filters, as I have some filters that categorize messages as "Primary" (so that they don't end up in other categories like Promotions or Updates).
But nothing is standing out, I even tried removing the part of the filter that assigns certain emails to the "Primary" category but that hasn't helped.
I can't figure out why they are staying in my Inbox view, as read-messages. It's a lot of clutter.
