[Missing Feature] EOS Camera Connect on iPhone - Remote Shooting doesn't fire external flash

[dd_chroma]

Remote shooting from an iPhone seems to have lost a feature that was working previously.

Scenario - group shot, you are in the shot and you have external flash setup. You want a remote shutter release from your iPhone. This definitely used to work I have previous photos of me doing this with the same flash setup.

On the current version of the iPhone app of Camera Connect when you hit the remote shutter button on the app it takes a photo but external flash doesn't fire. Go back to the camera and press the on-camera shutter button, it works as expected. 

This seems to be a feature regression. Something has been removed from the iPhone remote app.

Thanks for joining the conversation, dd_chroma!

So that the Community can help you better, we need to know exactly which version of iOS is running on your iPhone along with which camera and flash models you're using. That, and any other details you'd like to give will help the Community better understand your issue!

I've just re-tested with different flash units (hot shoe Canon, hot shoe Profoto, wireless Profoto).

It is now working for all combinations. So not a software regression, more a glitch somewhere in the connections.

Looking through the meta data on camera, every shot has a flash icon even the ones where the flash did not fire. The camera has acknowledged there is a flash connected. The difference being the icon there's a full flash symbol and flash symbol with an up/down arrow (was angled/bounced). The angled bounce symbol corresponds to the shots where the flash fired - which was done either by hand or 10s timer.

Didn't have time to reset and/or diagnose on the day - it was big group photo.

Camera Connect 3.2.40.36 (build 1409)

iOS 18.1.1

R5

On the day wireless Profoto.

Flash did not fire only on the attempts to use the Camera Connect app. Shutter button and 10s timer worked.

Which shutter mode where you using on the EOS R5? If you have it set to electronic shutter it won't fire the flash, so needs to be mechanical or 1sts curtain electronic. 

Secondly are you using the Live View display on the phone or just the bluetooth remote button feature?

[dd_chroma]

Not using electronic. I quickly tested by alternating between on camera shutter and app remote shoot when I discovered the flash not working. Have done this type of shot many times for the last few years. This is the first time it has failed. The live preview was on by default.
