Having the same issue with GoPro 8 - you get a very quick popup message (dissapears again) that says 'please upgrade your camera firmware'. I am already running version 2.0 - there is an updated version 2.01 but i dont seem to be able to download it. I usually do this manually but currently I get a red no entry symbol after filling in all the details on GoPro downloads. I never get the messages in either mobile or Quik desktop saying camera needs update. The fix is for a USB 3.1 connectivity issue. Has anyone else had similar issue.
Please make sure that the USB connection setting on the camera is set to GoPro Connect.
