Issue
After you create a Message Service (MNS) subscription, you are unable to receive messages or find relevant records in logs.
Cause
This may be because you configured the FilterTag parameter when you create the subscription. The parameter specifies the tag that is used to filter messages. Only the messages that have the same tag can be pushed.
Solution
To troubleshoot the issue, perform the following steps:
Check MNS logs and check whether no relevant records are found. For information about how to view MNS logs, see Log management.
Check whether you configured the FilterTag parameter when you create the subscription. Keep or discard the parameter based on your business requirements. For information about this parameter, see Subscribe.
