Missing entitlements rejection, yet when included still rejected

I have been struggling to pass the review process for various reasons, but it appears I'm down to one final issue.


***Necessary sandbox entitlement(s) might have been missing for the function.


My app requires a user login, and when I included the networking entitlement I faced the rejection of:

com.apple.security.network.client: Required to log in to our services


When it's not included I fail for the inability to log in, yet when I include it I am rejected for including it...


Any suggestions on how I can bypass this? I've requested a call, but the timeline was pretty vague and I'm just wasting time at this point.
