Issue in receiving calls & notifications

I have copied all codes from your Sample Android App for Sendbird Calls into my app. The app is able to receive incoming calls only if the app has made a call at east once. Same issue happens once the app is killed & restarted. Also the app doesn’t seem to receive push notifications for incoming calls in background but the token is registered successfully in dashboard.

Hi @Sooraj_R. I think it is weird behavior. If the FCM token is registered successfully, it should work. Can you share with us your app ID & user ID for looking into the issue?

APP ID 9A5EB080-89B1-48E8-8DC2-2A36B8D4B0B8 (registered email is User IDs used to test COAS0003 & COAS00004

We’re getting an error while sending push notification to your users. {"error":"MismatchSenderId"}
I think you have to check your FCM api key and FCM application id.(especially your google-services.json and FCM console). If you have any other problem, feel free to ask to me.

now seems working.had set the server key in the wrong app earlier

Initiating call from iOS app to android app , we are not getting calls. When app is in Killed state.

SendBirdCall.registerPushToken is not giving any error but still the push token is not getting registered into the dashboard.
