Issue description:
I imported a solution from a Developer environment to a Sandbox environment. Everything works well yesterday in the Sandbox environment, but suddely today all the data source connections in the app in the Sandbox environment are broken. It is also impossible to add the data source back since nothing can be found in the Canvas app studio add data wizerd (only tables and AI models can be added).
As Power Platform admin, I also checked if we have enabled any data loss prevention policy (DLP policy), but there is no policy on my tenant. I tested to create new Sandbox environment and even Production environment, the same issue for all the new created envionments. When I create a blank canvas app and try to add a data source, I cannot find SharePoint connector, SQL connector, Office365Users connector etc.
Is there any problem on my tenant settings rather than the DLP policy will cause this? or this is some kind of bug from Microsoft server side?
Same issue i found in the post below, but there is no good answer:
