Until yesterday I used Openfire 3.10.3 with Spark 2.7.4: no problem with offline messages.
This night I have upgraded to new version 4.0.0.
All is OK except the offline messages:
user A is offline
user B sent 3 messages to A
user C sent 2 messages to A
user D sent 5 messages to A
when user A connects to Openfire with the Spark client, he only has the first message of user B, the first message of user C and the first message of user D. The other offline messages are lost.
All the 10 messages are present in the Monitoring plugin.
Thank you very much.
