App stopped getting user account

Posted on by Dave10

Hello,

I have a canvas app that on start-up assigns User().FullName to a variable. It worked without fail until 1-2 weeks ago and then suddenly stopped The app opens fine and I have no issues with accessing any of the other Office products so the browser has authenticated me. I didn't make any changes that should have affected it.

- I did check to make sure that "Block 3rd party cookies" is unchecked.

- I'm using Edge browser Version 95.0.1020.44 (64 bit)

- I just checked and also have the same issue if you open the app within Teams.

Any suggestions on how to resolve would be most appreciated!

Hi @Dave10 ,

There is no reason that should be happening (and I actually set that in OnStart in every one of my apps) - what is the actual code you are using?

Hi @WarrenBelz ,

In OnStart I have Set(usr, User().FullName)

I also added 2 labels
Label1 with Text = User().FullName
Label2 with Text = usr

When the app starts, Label1 shows the name, Label2 is blank

The issue presents across multiple devices and users.

Do you have any navigation on App OnStart?

This is a ticketing system. Default screen is a screen with a gallery of the tickets. Navigation only if the application is started from a link to a specific ticket that is contained in an e-mail generated from within the App, in which case the edit screen for the ticket is opened in view mode.

Full Onstart content is:
Set(usr,User().FullName);
Set(varTktID, Value(Param("tid")));
If (varTktID <> 0, Set(varRecord, LookUp(TickIts, ID = varTktID)); Set(varEditMode,FormMode.View); Set(varEditHead,"View"); Navigate(EditTicketForm))

Hey Warren, I wanted to give an update.
Your thinking was correct. The issue was related to the Navigate. I ended up coming across this article.
I moved the Navigation per the instructions into App.StartScreen and everything started working again. Thanks for the clue.

Hi @Dave10 ,

Try putting it on the OnVisible of all screens you are likely to land when first opening - also ensure this switch is turned on

The new OnStart and StartScreen process is causing some problems with apps using conditional navigation code on deep links. Fortunately you can set that value elsewhere.

@Dave10 ,

Please beware that if you have anything set in App OnStart, you cannot rely on it to be set by the time the screen opens - I have issues with an app of mine where the form mode is dependant on an incoming parameter.
