Thanks for the feedback.
I think your issue here is the BarCode control not working properly for the first time when app loading.
Please make sure you have noticed the current limits for BarCode control:
Also please make sure your IOS version and the PowerApps version is the last version.
I have a couple of questions to help us investigate the issue. Does the Barcode never work when the app is first opened? How long have you waited/tried before closing and resuming the app? What rules, if any, are present in this app? Cheers.
" Does the Barcode never work when the app is first opened?
Not first time but when open normaly.
How long have you waited/tried before closing and resuming the app?
Not much, but works when resuming the app
What rules, if any, are present in this app?
I have the rules/permissions to needed to run barcode. eg. camera,notifications
Please try leaving the application open for 5-10 seconds too see if the barcode begins to scan. You can also try reducing the Scanrate on the barcode control and turning off Show Live Barcode Detection in the Advanced Settings.
