I submitted an undergraduate research paper back in early Fall of 2018. About 6 or 7 months later in Spring 2019 I asked for an update and got the reviewers report soon thereafter. The reviewer said they would recommend it for acceptance pending minor, mostly typographic changes. I made the necessary changes and resubmitted around July.
I hadn't heard back by the end of November, double the average time from submission to acceptance for this particular journal, so I asked about the status again. I was told by the editor-in-chief that he checked in with the referee and should be able to send the acceptance within the next day or two.
That was last month and I still haven't got any formal acceptance. Should I contact them again or am I just being overly concerned and impatient?
