I guess I'm not familiar with the term Auto Scheduler as it applies to Market Force. I thought you were talking about self-assigning, where you click that you want it and it is automatically assigned to you without human intervention. Shops you can't do will disappear from the job board you see.
I don't know why they would use that term for something that requires a human to assign it after you accept an email offer. I never read their emails so I guess I haven't encountered that yet.
Hope the help desk can give you an answer. Let us know what they say.
Time to build a bigger bridge.
