Another issue we encountered with the 2020.1 upgrade has to do with the Workflow history tab. When the Workflow history tab is in expanded mode of the sub-list and the user tries to save the form, it cannot be saved thus leaving the user wondering what went wrong. The Save button appears to be active but no action is performed on clicking Save. This issue was particularly found on the Item Receipt form and there are chances of it appearing on other transaction forms too. If the Workflow history is in collapsed mode, the user can save the transaction with no issues.
