Hello NHU-UYEN,
Thanks for using our plugins and welcome to the forums! I’m sorry you are having an issue with Event Aggregator. Let me try to help you find a fix for that.
In order to be able to give you better support please share with me your system information.
Also, could you please share with me the group URL and some individual URLs as well so I can run some tests?
Is it always the same 2 events that get imported?
Is there any difference between (all) the events? Like same / different organizer? Public or Private status? Anything you can think of?
Thanks and looking forward to helping you solve this.
Cheers,
Andras
