Input Reference Set Selector - Select Button taking long

Hello members,   Stuck into one special case. I implemented an input reference set selector with select page of 100 records (xpath). I have an onchange action which executes after selecting 1 or more records from select page.    When I am selecting the records on click of select button, it takes around 30 seconds before triggering onchange microflow. Also page goes unresponsive during these 30 seconds.   Any ideas?!

Do you have an On Change on the reference selector?

What if you try to create the same behavior as part of the select button on the select page. You could compare the originally associated objects to the newly selected objects and execute the logic.

You may need to change the context of your select page to your main object to be able to use that object as parameter for your select microflow.
