When we run canvas app on mobile or tablet device and running the app in background then it is not updating the data in dynamics 365. So my question is it possible to achieve this in powerapps? Please let me know.
What do you mean by "...running app in background.."? When the mobile device is sleeping/turned off or when PowerApps is closed?
Please see here: https://powerusers.microsoft.com/t5/General-Discussion/How-to-run-PowerApps-in-the-background/m-p/19...
Running PowerApps in the background is not currently possible.
Could you please share a bit more about the "running the app in background" that you mentioned?
Do you mean that you want to run your app when your Mobile device screen is locked or the app is in sleeping state?
If you want your canvas app to be running even when your Mobile device screen is locked or the app is in sleeping state, I afraid that there is no way to achieve your needs in PowerApps currently.
Running a canvas app when your Mobile screen is locked or the app is in sleeping state is not supported within PowerApps currently. If you would like this feature to be added in PowerApps, please submit an idea to PowerApps Ideas Forum:
