I submitted a manuscript to one of the weliy journals. The status was “Undergoing Initial Checking” on Scholarone system. After 3 days, the status changed to “Under Review” along with "Ed: not assigned" above it. It's been a month since this status change. Does this mean that it has been with the editors or has it be sent for peer review by referee? Why does the ed: not assigned but the status is under review?
Is it appropriate to write inquire to the editor about the status of my manuscript?
