Here are some possible solutions to troubleshoot when your podcast is stopping suddenly in the Podbean Android app:

1. Apps are sometimes killed every so many minutes when in the background for battery optimization. Please go into your device settings. Tap Battery. Then tap the menu button and choose “Battery optimization.” Tap the dropdown menu at the top of the screen and select “All apps.” Scroll down to Podbean- tap it and select "Don't Optimize".

2. The app will stop if you install some mobile phone management or battery saver apps like Greenify and 360 Security app. These will shut app services down and prevent them opening back up to save battery life. In this case, please make sure to disable these settings or apps to see if this resolves your issue.

3. Please check your Android Settings and make sure "Notification" is allowed for the Podbean app. This may help the system recognize the app is running so it will not kill the app.

4. Please check your network connection and make sure you’re playing the episode with a strong network connection.
