Mobile Illustrator App for iPad won’t upload artwork to Creative Cloud

The mobile Illustrator app on my iPad won’t unload to creative cloud the artwork I create with the illustrator app on my iPad. After uploading an illustrator file created on the ipad to creative cloud all the artboards upload blank. None of the photos or drawing are uploaded to the creative cloud folder from the illustrator app on my ipad.  But, artwork and photos I create in the version of illustrator on my desktop iMac is uploaded to creative cloud from my iMac. But, if I  work on the illustrator files uploaded to creative cloud from my iMac with my ipad, none of the additions or changes I make to the ilustrator file on my ipad will be saved back to the creative cloud. The files will continue to appears as they came from my iMac with none of the changes made on my ipad with the mobile illustrator app.  Is this issue fixable?
