Please pay attention to any issues around iCloud Drive folder. I had the previous version setup half way for one iCloud location ID, and half up for another ID. In terminal it should be that your iCloud documents get stored into:
/Users/<username>/Library/Mobile\ Documents/iCloud\~com\~hogbaysoftware\~Bike/Documents/
I’m not sure if this will happen, but if you don’t see documents that you did have in iCloud then they should be in:
/Users/<username>/Library/Mobile\ Documents/iCloud\~hogbaysoftware\~Bike/Documents/
