Springer with Editor I just submitted my paper to a Springer journal. The status changed to with editor and then decision process . I thought the paper will be rejected as it didn't pass the prescreening phase but the status went down to with editor again and didn't change for 10 days now.

Should I contact the editor Or should I wait?
"With editor" means an editor has been assigned, but no reviewers have been invited yet. "Decision in process" means the editor has made a recommendation to the editor-in-chief.

I'm guessing that the editor-in-chief disagreed with the editor, and either assigned a different editor or sent the manuscript back to the editor. I would say wait, although if it goes another ~1 week without the status changing I would write to the journal asking for an update. Two weeks should be sufficient for the editor to either make a decision, or to invite reviewers.
