I appreciate your time bringing this into our attention, amit6.

We can try to do a manual update by going to Banking tab and select Update button to have the transactions downloaded from your bank.

If you have any error message showing, you can check on this article on what to do if you get a bank error or can't download transactions in QuickBooks Online.

Also, I recommend to get in touch with our QuickBooks Customer Care Team to further check on it.

Feel free to let us know if you need any help. Have a nice day.
