I'm sorry to hear that you're experiencing issues with saving your Data Schema in the Analysis tab. Let's try to troubleshoot this together. Could you please confirm if you are receiving any error messages when you attempt to save and publish? Additionally, please ensure that the data you are trying to save matches the structured data schema format required by the system. If everything seems correct on your end, there might be a temporary issue with the service, and I would recommend trying again after a short while.
If the problem persists, please ask support for more info on this, as they may need to look into the issue more deeply or provide a solution specific to your case.
