It's interesting that FW 1.2.0 and 1.3.1 are there now, but not 1.3.0.

I just noticed that my personal R5 II is still on 1.2.0. I wonder how long to wait for the update.

Probably because 1.3.0 is known to have bugs, and has been directly superseded?

They all have bugs.

Have you used 1.3.1?

I installed the new firmware and photographed swallows in flight this morning, and didn't notice any issues.

I'm in no rush. My R5II is working well for what I need it to do and will wait for more user feedback.
