This week Sony issued a new 2.0 firmware update for the A7III and A7rIII. But if you are using third party batteries be aware that there a multiple reports of issues:

1) Some batteries are still allowed to be used but the camera won’t show you how much battery life is left and there will be a pop up reminder from time to time

2) Some are completely useless. The camera tells you this battery is not qualified and automatically shut down
