One child dependent visa delayed

I applied for my Skilled worker visa and my wife and childrens Dependent partner and Dependent child visas respectively on 6th Oct. i am grateful the visas were received for all of us on 24th Oct except for my 12 yr old daughter. Till today I am waiting to receive it. All the supporting documents were same for all children. I have not received any queries from Home Office by email regardinf any document.

Any one faced such an experience. What can be the cause of delay and is there a way to expedite it as I want to join my Job.

I found the glitch. There was an email from homeoffice on 15th Oct asking for Birth certificate and consent letter. But it ended up in my Junk email and I never noticed it all these weeks. It had a 10 days time period. But since I only noticed it yesterday, I submitted the documents by email 24 days later but hoping UKVI will accepept and awaiting UKVI decision.

Dear friend, how did you solve the problem? We have got the same issue. We have already applied for our 3 year old son's dependent visa, but we didn't upload the consent letter. What kind of letter do they ask for?

Dear Yaqut,

You can google for a template. A lettern on plain paper mentioning the we Mr. x holder of passport no. Y father of Child name and Mrs. y holder of passport no. Abc hereby state we dont have an objection for the child to have a UK deendent visa. We will stay with our child name xyz at a rented apartment in location X. We provide our consent for his visa application.

Both should sign it and email it to them. They would have sent you an email regarding the same. Subject line mention the application reference number GWF....

Wish you good luck.
