Firebase is deprecating Server Keys and replacing them with Firebase Cloud Messaging Tokens, and occasionally Server Keys may just stop working. If you still use Server Key as the API key when configuring your Pushwoosh Android app and get the MismatchSenderID error, please make sure to use Firebase Cloud Messaging Token instead of the Server Key.
