I applied alone, with no family members included. But i have a visitor visa and SP numbers on the tracker even i am alone for my application only.So you are single. You said SP and TRV which usually on this forum means two people - student and child or student and spouse. When you apply for a SP, you don’t apply separately for a TRV too. A TRV is part of the SP.
i got it 18th Dec and still no PPR by E-mail . Web form rased 2 weeks ago but still no response.
