How are you uploading the file to Creative Cloud? If you upload an xd file to the cloud using the web interface, the file will not be accessible. This will not update the file format.
you have to open the old format .xd file in the XD desktop app, then choose save/save-as and choose the "Creative Cloud" folder (or a subfolder inside there) as the location. Alternately, you can save it with the latest desktop XD app anywhere on disk, then move it to your Creative Cloud folder in your finder. Either of these will trigger the background task that uploads the file from your mirror directory to the cloud in the proper format.
I save thats file in my local drive, then I drag to my web interface adobe cloud. So cause that it detected old file?
Short answer: do not use the web interface. Use your OSX or Windows finder to put the file in your Creative Cloud folder. It's a cloud mirror folder we install on your disk. You can also save the document directly from XD into this folder. A background process will convert it to a cloud document and upload it to the cloud for you
Longer answer: when you save the document into the Creative Cloud folder, it's no longer a file. It's a cloud document. It's more like a database. It has special features as a cloud document that a file does not have.
When you upload a file via the web interface, it remains a file. You can get the file back from the cloud later, but it will not support any cloud functionality while hosted in the cloud
