Hello.

See the answer to your question is both yes and no. No, because you have so much experience and you knowledge ,then it will not be a problem. If you have something to show as proof of your engagement in those four years, like a gap certificate. Experience matters a lot and you have 7+ years of experience which will work for your benefit. And yes, because some company might find it faulty and not eligible. But there are a lot of companies who are looking for employees with experience. So you're good to go.
