We have an SNS queue with multiple subscribers (2 * SQS, 1 * email, etc.). However, we only get the notification for the last subscriber. I.e. when each of them is registered alone we get to notification. So as far as I understand each of them alone is configured all right.
I didn't find any relevant AWS documentation about it (limit of subscribers, policies, etc.)
Would love to hear any hint about it. Thanks in advance.
Solution: the issue was the order in which the SQS permission-subscription was created in. The correct order is detailed here. If you do step 3 before 2 it won't work.
