We have experienced weird behavior from the push notifications starting sometimes late last week. Our users have begun receiving notifications not destined to their devices, and we have received many reports of similar cases.
We have checked our codebase and logs and nothing seem to have changed, be it for the recent setup of notifications with FCM. We are using exponent-server-sdk-php on a Laravel project to send notifications.
It seems the tokens are targeting more than one device. We were looking to know if their was any known issues with the expo notifications API, as there are many things changing day by day like the inclusion of FCM.
