UK Spouse Visa From Pakistan ( Application has not been Straightforward) E-mail

[Everyday4u]

I would like to ask if anyone has received " Not Straightforward application" E-mail from Home Office? My Timeline is as followed:

Online Application Submitted: 15th November 2017
Category of Application: Non- Priority (Standard Application)
Type of Application: Dependent Settlement Entry Clearance (Wife+child)
Biometrics appointment: 20th November 2017
Documents sent to Sheffield: 24th November 2017
Documents Returned: Second Week of December
(Visa Assessment Center) Sheffield: 6th February 2018 (Unfortunately, applications have not been
straightforward and unable to decide within target standard time.

No Interview (inquiry) call received neither to applicant nor to sponsor yet. it has been 53 working days since bio metrics are taken.

Did anyone receive same E-mail recently? It could be standard E-mail to buy more time? I am bit concern now as they have not taken IHS charges for the child due to bug in system. Any suggestion or advise is appreciated. Thank you.
