Issue/Introduction

The Home > Timesheet page is working as expected for most users, but the page never loads (just says Loading...) for two users. 

Environment

Release : SAAS

Component : AGILE CENTRAL

Cause

Third party addon or plugin running in browser.

Resolution

Both users had "ublock" running. When disabling it for that page, all items are loading as expected.
