I have submitted a manuscript and it is showing the status "Editor Assigned" for nearly five months. I have contacted the editor after four months and they appraised that due to editorial workload they are taking more time than usual. One month has been passed since this incident and I am getting worried if something is wrong. I have done further work on the same topic which has been under revision in another journal and it is still in the same status.
Is there something which I can do or should I wait?
Is it mean that my article is of lesser interest to them and they are giving it the least priority?
