Hi all,
I was in a similar situation, and this conversation was really helpful. So I thought to share my experience with the home office HO.
I applied for a dependent visa for my daughter in 29/6/21 and then in 14/7 I received an email form HO saying the application was successful and I should receive the BRP with 7 days. I waited 10 days and nothing arrived then I filled in the link for not receiving BRP.
I received an automated email form HO says we’r experiencing larg amount of request and it could take 40 working days to get back to you!!
Then I emailed the brp delivery team and they got back to me in 20 mins saying we can’t do anything and we have told the department about it and a caseworker on it!
Than I decided to wait since there is no much left to do. Then all of sudden I received an email from HO in 18/8 saying you will receive the brp in the next 48 hrs, it was sent with a courier and they will contact you with 24 hrs . The flowing day TNT sent me an email that brp on the way (8am-8pm thing) and at 9:20am someone called me to open receive the brp (finally in my hand

).
In short, the decision took 14 days after I made the application. The brp arrived after about 5 weeks from the decision letter.
It is so stressful that there is no tracking number.
By the way the date of issuing on the brp is 16/8 witch means all the delay was from the brp department, not the TNT
I hope all of you who are waiting for their brp to receive them soon
