Hi @blanghorst,
Have you solved your problem?
Based on the needs that you mentioned, I think it is not necessary to change the Status field (Combo Box) control from "Edit selection" to "Edit Lookup". In addition, it is also not necessary to initialize a variable to store the Status value.
I have made a test on my side, please take a try with the following workaround:

Set the DefaultSelectedItems property of the Combo Box control within the Status Data card to following:
If(
SharePointForm1.Mode=FormMode.New,
{
Value:"New"
},
Parent.Default
)
Set the OnSave proeprty of the SharePointIntegration control to following:
SubmitForm(SharePointForm1)
Set the OnSuccess property of the SharePointForm1 control to following:
Patch(
'20181130_case3',
SharePointForm1.LastSubmit,
{
Status:{Value:"Pending"}
}
);
ResetForm(SharePointForm1);
RequestHide()
On your side, you should type:
Patch(
'YourSPList',
SharePointForm1.LastSubmit,
{
Status: {
Value: "Pending"
}
}
);
ResetForm(SharePointForm1);
RequestHide()
Please take a try with above solution, check if it help solve your problem.
