I also have a rejection. Works on in Test flight with sandbox user. I see the "RED" dot in "Subscription Group Display Name" and 2 x "Developer Attention required". I have updated the name and can see its all yellow and status is now "Waiting for Review". I iwill update here again once I resubmit. I checked all the tax, bank etc. All seems

Make sure you resubmit the app. They will then read your reply. Look out for any "red" dots in the In app section that may need attention before resubmitting.

Thanks. this worked... The instructions are mis-leading.
