Sharepoint 2010 Workflow can no longer be published on Sharepoint 2013 for our Online site

Also disappointed with the management of this issue. I do have access to the Health Service for our tenant and there is nothing posted about this incident. Being unaware of the current situation, we tried to publish updates to several SP2010 workflows, which are now broken.

Feels very much like Microsoft is trying to hide this issue, which is having a huge impact on many businesses. And we do still need SP2010 workflows since both Flow and SP2013 are lacking some of the same functionality.
