Uploading to Creative Cloud desktop app problem

I am trying to upload videos from an SD card to the Creative Cloud desktop app which I believe is supposed to allow uploads of files of up to 5GB. I am only trying one video at a time of less than 5GB but I keep getting a message saying that my file is "over the maximum size (1GB)". Everywhere I look says that the limit should be 5GB for the app so I am confused and was wondering if anyone knows why this might be and how I might get round it.

Thank you
