Companies House Filing History

  • Polling for submissions via the Companies House Filing Log, where submissions contained at least one Confirmation Statement with director verification pages, will no longer result in the application crashing.

  • Checking status via the Companies House Filing Log now works as expected in all scenarios and no longer displays the 'Companies House Filing History already open' dialog. A user that had this screen locked must log in once after update to clear the lock.

  • Resizing the product interface main screen is now possible so that all options are accessible when a size other than the default screen resolution is used.
