Timelines of cases, accounts and contacts are no longer refreshed when you go to a new tab, or open a new entity in the same session.
Example: Open an account, in the account window, click on a contact: a new tab opens. When you go to that tab and return to the account, the timeline of your account will be empty (it mentions "Get started Capture and manage all records in your timeline") > workaround is to click on the refresh button and you will see the details in your timeline again.
This behavior started last week and occurs only in the customer service workspace app. Agents working with the customer service hub do not have that problem.
