Set Language from DropDown on AppStart

[PierreBreau]

I am building an app in power apps, I have a dropdown which toggle the language from French to English, this part works fine. My problem is when the app starts there is no language selected so all my labels for example are empty even tough the Dropdown is set to English. 

This is the OnChange code of my dropdown:

Set(gblSelectedLocal, ddlLanguage.SelectedText.Title); 
UpdateContext({gblSelectedLocal: ddlLanguage.SelectedText.Title}); 
lblSelectedGlobal.Text = gblSelectedLocal;

so I try adding this code to the OnStart of the app but nothing is happening. I also try setting up the glbSelectedLocal variable on start as well but it seems like the OnStart function does nothing. 

Anyone have a good way to approach this? I'm new to PowerApps as well.

@PierreBreau I just tested it out and it works fine. So I am curious as to why it isn't working for you. Can you try this code in the OnVisible of the screen where you have the dropdown? I want to first make sure that it works for you.

I ended up creating a page with a language selection button. When the user click the button it set the variable and then bring them into the app. 

Sorry for the late reply on this and thanks for trying to help
