Navigation in App.OnStart not allowed anymore (New App.StartScreen??) - Deep Link problem

[MarkusG]

Hi,

Issue Description:

Since some days I have the problem that the deep linking parameters that I set in App.Onstart are not working anymore. 

I want the users that use the deep link to navigate to a separate page with all the details about the entry.

Apparently it is not allowed anymore to use the "Navigate" function. There is now also an App.StartScreen property and I'm not sure if that is new or was there all the time. I was not able to find any information about it online.

Does anyone know how to fix this, so that the deep linking is working again??

Parameters in App.OnStart:

Set(varDemandIDView, Value(Param("DemandIDView")));
If (varDemandIDView <> 0, Set(varRecord, LookUp('Project Portfolio Management', ID = varDemandIDView)); Navigate(ScreenDisplayDemand_OnePage));

Error Message:

I have a small issue with this:

I am seeing the error: "Navigate is not permitted in OnStart. Use the StartScreen Property instead".

The problem is - there is NO "StartScreen" Property.

So anyone know how I can navigate to a specific screen on App load?

Enable Navigate function in AppOnStart is 'on', but I still get the navigate is not allowed error. This occurs in all of my existing apps where I have used Shane Young's deep linking method:

Set(varEmpID, Value(Param("RecordID")));
If(varEmpID <> 0, Set(varRecord, LookUp('Request Form', ID = varEmpID));Navigate(Screen2))

Greg's article was no help to me.
I really don't care how long it takes the app to load, and I guarantee that not a single one of my users care if its declarative or not. I just my stuff to work again. 

So frustrated and sad.

Thanks heaps @Mostafa . This solved my problem. Is there any danger this will be turned off/depricated in the future?

I was trying to implement a Deep Link and hit this issue. 

My workaround for this limitation is to add a Timer Button,

Start = false

Duration = 1000

Repeat = true

Reset = true

AutoStart = true

and OnTimerEnd, if the global variable it not blank, then redirect to another screen

If(
!IsBlank(gbl_DeepLinkRN),
Navigate('Deep Linking Screen');
)

Yes, I ended up doing the same. is just cumbersome as there is a small delay until the timer expires.

Click on App and input this under StartScreen

where the ReviewDay and Dashboard are screens you've already created in your app.

Now for the url: supposing the url is https://apps.powerapps.com/play/e/default-48b3-a751-e33af7c1f8fb/a/0d27af4d-c7121a?tenantId=9e0748fb add this without the double quotes "?ReviewD=ReviewD"

The app will navigate to ReviewDay screen if your param value is ReviewD else it will navigate to Dashboard.

Hi there, just wanted to let you know that this workaround was quite simple, but that it caused an unexpected error in my app and my deep link feature didn't work.

You can share the error here and I would assist.
