Hi Vikram,

Welcome to Box Community and glad to assist!

I have created a ticket and a member from Product Support will get in touch, please keep an eye out. 

Thanks for posting!

My Box tasks, notifications and collections also have been failing to load. Additionally, I cannot assign new tasks to my collaborators. This occurs on both Chrome and Safari browsers as well as on different devices (PC, Mac, iPhone). I've cleared cache and history, and restarted my computers
