Mismatched device token for FCM

I try to use FCM push with my android app. I succesful get token on device and send it to sendbird server. But push doesn`t work.
I tried FCM push notification tester and get this error: “Couldn’t send push notification. Mismatched device token. Please enter correct device token for the provider.”

Hello @Roman_Panev,

Welcome to the Sendbird Community.

This is actually a known issue that was discovered earlier tonight. Currently, the Push Notification testing tool does not work with FCM due to a bug that was introduced. Please note that this does not impact actual pushes and only the testing tool.

As soon as a fix has been released, I’ll comment here.

Thanks,
Tyler
