Client got build without the update is approved

I was having first version of my project uploaded on 4th April 2018 and it was approved at 5th April 2018 and then it was purchased by many users and after that I have uploaded update on 28th April 2018 and till today (1st May 2018) I have not received any confirmation about the approval of the new build. But one of my client is facing issue with the file which I have added new in the build which I have uploaded on 28th April 2018. So my question is, if I have not received any notification about the approval of my new build, how my client got the error in the file which I have added in new build?

Can they get the updated build without approval from codecanyon?
Please resolve my query as soon as possible.

Thanks,
Saurabh
