Hi @shabinder-singh, thank you for raising the issue. By any chance, were you able to reproduce the issue? Can you share an MCVE to help us investigate the issue? fa

Aside from that, does the issue occur on certain devices and/or android versions? Can you share the dependencies and the complete stack trace? Please ensure that there are no PII's from them. Thanks!

Unfortunately, I couldn't repro, hence unable to provide any concrete steps or a mcve, fa ?

Aside from that, does the issue occur on certain devices and/or android versions? Can you share the dependencies and the complete stack trace? Please ensure that there are no PII's from them.

Thank you for sharing that @shabinder-singh. Looking through the stack trace, the ANR is caused by CloudMessagingReceiver onReceive method that's blocking the main thread.

By any chance, can you share any code snippets that are related to Firebase Cloud Messaging? This will help us investigate this further. Thanks!

[shabinder-singh]

I think we only have clevertap configured, nothing custom or any service extending FirebaseMessagingService or CloudMessagingReceiver, especially in our TV builds.

Thank you for that info. Just to clarify though, you’re not using Firebase Cloud Messaging for your notifications? I’m not familiar with Clevertap. Could you share how you receive notifications? Thanks!
