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

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.

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
