While using the Chat UQ API, why are chats not being delivered and error messages in the logs are referring to maximum message size quota for incoming messages being exceeded?
Chat UQ API
This happens when specifying a starting sequence number of zero and, eventually, too many messages build up and are returned on the 'retrieveMessages' API call to be processed. Errors observed in logs indicate message size quote is exceeded.
A null should be sent in the starting sequence number field and let the chat server keep track of which messages have been sent. The starting sequence number should only be used to attempt to recover from a system problem that caused the Chat UQ API to miss some messages that had been sent.

Please refer to the "RetrieveMessages" documentation on how StartingSequenceNumber should be used:
