Black screen in canvas app

Posted on by Vektori1

When the user is in the play mode of the canvas app, and waits long enough, the entire screen turns black.

I have tried to advice users to remove the temporary files and cookies between the machine and the browser. I also tried switching to an older authoring version, but that didn't work either.

Have others experienced similar issues?

@Vektori1 HI,

I suggest that try those:

If possible that ask the user to logon a different computer.

Disabled some new features in the settings.

Export the solution and import to another environment for testing.

Good luck.

What does going black mean?

Has the computer gone to sleep?

Are they being logged out?

Are these laptops or desktops?

Does the application that they are using work?

Show a photograph of the screen.

I haven't experienced this issue.

When did it start?

Did you publish your app recently?

Does this affect all users?

What about other apps in the environment?

What's on the canvas app screen before it goes to the back screen?
