I've sent my manuscript to a high impact journal and it took them a year to return the manuscript to me for corrections and it has been a year since then without further updates. Initially, I receive a reply when I send email for update. However, for almost 6 months I receive no reply when I send email to the editorial assistant for update.
I would like to hear from senior colleagues and those who are likely editors of academic journals here the possible reasons for taking such a lengthy time to make a decision on a manuscript and what would you advise me to do.
