The first time I submitted an App, it was at this time of the year and it took more than 30 days for them to get back. So I think being short staffed during this season, along with the fact that it was my first submission, caused a longer delay. Now my apps are approved in less than a week.
I would say, if your app status still shows up on the developer console as being submitted, then you just may have to wait longer and you don't need to be concerned.
