I have several workflows on various lists of my SharePoint online site, which are set to fire off on item creation, edit or manually. Recently, the workflows don't start on any of them and I get the following error message:
Suspend this workflow

I have full administration permission (Full Control) and am also a global admin for this tenant. Until 1-2 days back, I was able to run all workflows normally. Any thoughts?
Update 19 March: After doing several tests, the problem has been isolated. The issue is that no actions are working within the app step. It also seems that the Workflow app has lost all permissions to perform any actions on the entire Office 365 tenant.
The workflow app has already been provided 'full control' earlier and all the workflows were working fine until few days back.
