Follow Up on Application

So about a month ago I applied to a job and a few days later I received an email asking me to do a video questionnaire. It was basically a one way interview where I film responses to questions written in text. After a week I sent an email to the recruiter who sent me the initial email and received no response. It's now been 4 weeks since I submitted the video interview and my application status says "In Progress". The date of the status has updated multiple times, the most recent being last week, but the actual status remains the same.

Should I send another email? Or perhaps I should shoot a message on LinkedIn?
