Out of the blue my desktop, laptop, and iPad no longer connect with my MG6821 printer. Error message 300. I checked all the connections and there good. I tried resting the printer and followed the instructions to reconnect my computer to the printer no luck. Iam running Catalina OS 10.15.7 on the computers and when attempting to connect through then canon support site the newest OS download listed was 10.14. Is the MG 6821 still being supported?
