'Firebase Cloud Messaging - Receiving notifications from topics that i'm not suscribed to
I have a very strange issue with Topics. Some users tell me that they receive notifications from topics that they are not subscribed to. How is this possible? I saw a screenshot showing the notification.
I use https://iid.googleapis.com/iid/info/[token]?details=true to check their subscriptions, but in the rel array of subscribed topics don't appear one topic and still receiving push notifications. Is it possible they have another working token?
Has anyone had a similiar problem? Thanks in advance.
