I would exercise a bit more patience as some response times are 3-4 months. If the reviewers have already conducted their review, that is a good first step. It is probably on the editor's desk and asking for a response may not hasten the decision.

Dear, write to the editor and find out the cause of the delay and know the next decision.

Thanks Dr. Karin L. Becker and Dr. Emmanuel Ifeanyi Obeagu for your answers

Hi Yasir，

I have a manuscript submitted to the ACI journal， and it stays on the “ Awaiting MRC Decision ” status for more than one month also.

May I know how many time your paper finally passed this status to the next step?

and, what's the next step (for your paper)?

Thank you very much!
