VBA using multiple Application.OnTime; one seems to fail - vba

Question

This is part of a much larger macro that has multiple instances of Application.OnTime that work just fine.
My issue with this one below is in WaitForPriceVolume() when it gets to the For Each loop and the If is true, it doesn't go back to the procedure WaitForPriceVolume(). It circles back to all the procedures that were called before, effectively just doing the Exit Sub as if the OnTime didn't exist.
When I strip out just the below code and add fixed values for the global variables being used, the Application.OnTime works. It's only when I plug it back into the bigger macro.
Sub BDP_PriceVolume()
Dim lsStartRange As String
Dim lsEndRange As String
Dim lnStartRow As Long
Application.ScreenUpdating = True
Application.Calculation = xlCalculationAutomatic
Set sht = Worksheets("Variables")
' Use gvList
lsStartRange = "C" & gnStartRow
lnStartRow = gnStartRow + UBound(gvList, 2)
lsEndRange = "C" & lnStartRow
sht.Range(lsStartRange & ":" & lsEndRange).Value = _
"=BDP($A" & gnStartRow & "&Variables!$A$2,Variables!$D$2)"
lsStartRange = "D" & gnStartRow
lsEndRange = "D" & lnStartRow
If Worksheets("Variables").Cells(3, 3).Value <> "" Then
sht.Range(lsStartRange & ":" & lsEndRange).Value = _
"=BDH($A" & gnStartRow & "&Variables!$A$2,Variables!$E$3" & "," & _
"Variables!$B$4,Variables!$C$3," & _
Chr(34) & "BarTp=T" & Chr(34) & "," & _
Chr(34) & "BarSz=40" & Chr(34) & "," & _
Chr(34) & "Dir=V" & Chr(34) & "," & _
Chr(34) & "Dts=H" & Chr(34) & "," & _
Chr(34) & "Sort=A" & Chr(34) & "," & _
Chr(34) & "Quote=C" & Chr(34) & "," & _
Chr(34) & "UseDPDF=Y" & Chr(34) & ")"
Else
sht.Range(lsStartRange & ":" & lsEndRange).Value = _
"=BDP($A" & gnStartRow & "&Variables!$A$2,Variables!$E$2)"
End If
sht.Range("C" & gnStartRow & ":" & lsEndRange).Select
Application.Run "RefreshCurrentSelection"
Application.OnTime Now + TimeValue("00:00:03"), "WaitForPriceVolume"
End Sub
Private Sub WaitForPriceVolume()
Dim rng As Range
Set rng = sht.Range("C" & gnStartRow & ":D" & fnLastRow(sht, "A"))
Dim cell As Range
Application.ScreenUpdating = True
For Each cell In rng
If cell.Value = "#N/A Requesting Data..." Then
Application.OnTime Now + TimeValue("00:00:03"), "WaitForPriceVolume"
Exit Sub
End If
Next cell
Call DoneWaitForPriceVolume
End Sub

Own stupidity. All the other instances of OnTime came at the end of the code, so the macro had nothing left to do until the OnTime triggered and I forced everything to circle back to the main macro. I hadn't done that in this case. Problem solved. This haunted me for a week
