Is your device on battery-saving mode? If so, please turn it off.
Go to your smartphone's "Settings"
Click on "Apps & notifications"

Click on "Special app access"
Click on "Battery optimization"
Find the Acast app and make sure to disable/enable the app to play in the background
Please note that the terminology can differ between devices, but look for Apps / Battery Optimization in your Settings page.

Are “Notifications" allowed for the Acast app in your device Settings? If not, please allow notifications for the Acast app.
