Timecard loading issue

Hi,

Employee Time Card Period : 16/08/2025 to 29/08/2025

when an employee want to add his time card for Aug 18 and clicks on the above time period and fills out the necessary fields and submits the timecard. After that when he tries to enter the existing submitted timecard to make changes. The page keeps buffering the entire time. This has been happening for most of the employee lately. Could someone please help me with this?

Is it because of any certain roles or privileges that are missing or something else?
