See the exchange below to have more context.
If you are more lucky with a Mark3 than me with my Mark2, the phone app could still working.
If it's the same than with an R50 on Camera Connect, you have an option to connect it with Bluetooth to use your phone as a remote.
Use the 2 seconds delay on the camera so you will not always be with the phone visible on your photos.
It's the better solution I have while waiting for Canon to correct the "C" mode bug.
