I have an eos 90d and get the app/camera to talk to each other. In my smartphone settings i turned blue tooth on/off and it found my camera. I then ran the canon connect and went through the instructions , after a very long time the camera reported target not found , i have looked at various tutorials and have no idea what i am doing wrong.
Update for anyone who sees this , canon finally confirmed the app does not work on android 10 or above , android is now version 12
This seems poorly handled then on their part, granted I don't think DSLR users are heavy users of the phone app, but that is very surprising to not keep it up.
