Fiori MyInbox showing nothing on All Tasks

Hi,

SAP Fiori Myinbox is configured but its showing 0 tasks.

There are tasks in myInbox with (READY, COMPLETED) in the back-end ECC Inbox but nothing is being displayed in FIORI.

What I have checked so far:

1.  There is no error found on front-end in IWFND/ERROR_LOG, Fiori MyInbox shows 0 tasks.

2.  We have implemented note  2153599 

Here is the service details when I checked.

Thanks
