I am facing the same problem. I uploaded a new version for my existing app and initially got rejected. Then after resolving the issues mentioned by the reviewer, I uploaded another new version on Apr 30. After that it went to In Review state for almost 3 weeks. Then I tried to change the build number and again uploaded, but no luck. It again went to In Review and it is still in that state.
I tried to contact the App Review 3 times by submitting the details, but every time got an automated response from their side. How can we contact the App Review team to resolve this.
Does anyone has got any resolution? Please help.
