Is it normal for a new app to be In Review for 5+ days??

I've built a new app and have submitted for review. It went into review almost 6 days ago. But no feedback, no rejection, no approval? Did the sole person reviewing my app suddenly die or something? Or maybe quit without finishing? What can I do? I've never had an app take more than a few hours once it goes into review. This is incredibly frustrating.

mine has been three weeks! with zero feedback, im beyond frustated.

I am the same. It was submitted for review on October 28th and the review started that evening. I also saw the reviewer logging in from the backend log, but the status has not changed since then. It has been 10 days and I cannot contact the developers. I really crashed
