do not waste your time with t8s app. I had probs with hero6, now hero10 the same. finally managed to get connected and enable preview after lengthy struggling, but some days later same problem, app sees the camera, but cannot load perview, cannot load media. nothing changed since last time when it was working. otherwise the app is useless, just download your files to your storage and edit / manage with any sw you like.. do not waste your time here
