@Shania_C the option you've detailed is not helpful for most customers. Our business does not access invoices from the Sales tab. When we open an invoice through the search feature, we used to be able to see the invoice Activity History right there at the bottom of the page. 

This feature was essential to our workflow.

The "new invoice experience" has left our business in very bad position as it was implemented without warning and has been very time-consuming.

We would appreciate assurance that this feature will be reinstated as soon as possible. Our company is already researching new accounting options in the meantime.
