The Hot Folder is not updated with the captured images from my Canon camera.
Why does this happen?
The Canon tethered process sends the file to the computer with a specific "name" that does not reflect the file name that you ultimately see. This temporary name is then changed to the final name once the entire image is transferred. As Capture One tries to access the image at the moment it sees it (prior to the moment it is written finally), it is actually trying to access the file which is supposed to appear only some moments later (obviously, this file does not exist yet due to the name change). Therefore, the file does not show up in the Capture Folder without a refresh. The Remote Shooting feature of Canon EOS Utilities modifies this behavior so that the file is sent from the camera with the same name as visible.
How to fix this issue?
With Canon cameras, when shooting tethered using Canon EOS Utilities, it is necessary to turn on a feature in Canon Software to allow Capture One to effectively use the Hot Folder Feature. Once the Camera is connected to EOS Utilities, please turn on the Remote Shooting feature in EOS Utilities.
After the first image is shot, a subfolder will be created within your designated destination folder. Be sure to establish this folder as the Capture Folder within Capture One and turn on the Hot Folder feature by navigating to Camera -> Hot Folder Enabled.
