The A6400 and Godox flashes (UPDATE 1)

The A6400 seems to have problems with the Godox TT350S. Here are a set of pictures of my closet, taken with three different flash units - the 350s, the Godox 685S and the Sony FVL-F32M. Settings are Auto TTL, No flash or exposure compensation, exposure compensation ambient only.

I am curious to see if other people are having some problems with Godox flashes on the A6400. All the flashes work with the RX10IV that I use a lot. Thanks for looking.

UPDATE 1

Additional testing. I took pictures with my 90mm macro and the tt350s. Interestingly, the flash worked fine.

And the 105mm end of the 18-105 is still underexposed (it was as before).

Thanks for the response. The TT350S works with every other Sony camera I used with it. Except the A6400. The TT685S works fine, but not the TT350S. I have two TT350S and they exhibit the same behavior. I actually returned my first A6400 because I thought it had a problem. It turns out the A6400/TT350S is problematic (at least for me). Maybe a firmware upgrade can fix this.

I bought a used HVL-F32M so that I can have a compact flash to use with the A6400. Works well. I used to have an HVL-F43M but I sold it when I bought some Godox flash units. They work well with the other Sony cameras, but with the A6400, the smaller flash unit seems problematic. Thanks for the response. And great POTW.

I have the firmware up to 1.8 when I did the testing. I added two more pictures in the original post. It's all sort of strange.
