Hey @mosapei and @m3_1 , I am not on the App Review Team, but our team was able to do a bit of digging and found this post that seems to have a few solutions from other developers who encountered a similar issue.

Hope this helps - if not, just let us know in this thread and we can take a deeper look. Our team does not generally deal with app review submissions, but we can try to provide some next steps.
