I just upgraded some MV21 and MV71 cameras to the latest 4.3 beta firmware and the result is impressive.
It used to take 5 to 10 seconds before they would start showing live video and now that is down to just a few seconds.
Well done Meraki software developers!
I'm just about to deploy it. Thanks for the heads up. It also specifically mentions a bug I ran into.
