I can tell you that the print continues on after the filament runs out and the print is ruined. Just happened to me today. Running firmware Alt - 21.12.21
I get this problem too. The error is in Canvas. There is no error on the P3. Everything looks OK in Canvas. Everything shows as connected in Canvas and the P3. I tried the reset of the browser and that did not help. I tried a restart of the P3. I tried a factory reset of the P3. This very frustrating. I can only print the keychain from the initial setup. I have enough keychains.
