ETAG Mismatch - Previously Posted Solutions Not Working

Hello, for give my frustration.  I have been working on this issue for days now and the solutions don't seem to be working.

 

Two solution references seem to be Article 1 and Article 2.

 

I think I am doing what both of these articles show the fix to be.  However, results are still an ETAG error.

 

DataSource is a SharePoint List.

This is a Custom Canvas App.


List Screen (Using a Data Table Control):

Navigate(
    ScrDetail,
    ScreenTransition.Fade,
    {
        FormState: "View",
        SelectedNCR: DataTableNCR.Selected
    }
);

 

Save Button.  First save is good.  Second results in ETAG.

Refresh(B20);
UpdateContext({SelectedNCR: LookUp(B20, ID = SelectedNCR.ID)});

Patch(
    B20,
    LookUp(B20, ID = SelectedNCR.ID),
    {
        Responsibility: Dropdown_Responsibility.Selected,
        ResponsibilityText: Dropdown_Responsibility.Selected.Value
    }
)

Based on the referenced post and this post, the solution seems to be refreshing the data source before updating.  Yet I am doing this and it is still producing the ETAG error.

 

Does anyone have any suggestions or see what I am doing wrong compared to the referenced solutions?

 

Thank you in advance for any recommendations.

Is B20 a data source or a collection and if it is a collection how is it set?
