I have taken the local notification app and simply added the schedule method inside the notifcation onTriggered event so that I can get continuous alerts, however it stops after three messages.
Works fine on Windows, don't have an android to test.
Thank you for asking the question in our community. We have a "Local Notification" sample (you can find it by opening AppStudio Desktop > click on New App button > search for "Local Notification" ) and I have tested it on an iOS device. I was not able to reproduce the issue. Do you mind providing us more information? What is your device model? Can you also provide us the code snippets?
