Looks like Apple is getting the non-update first. The What’s New doesn’t show anything different, but the app description gives the text that Tenkara referenced about being able to select available Bluetooth audio sources connected to the hearing aids. See the screen shot below I swiped from my wife’s iPhone. It’s frustrating to see it on iPhone first since Phonak readily acknowledges that more people run Android and that there is a big demand for the Marvels from the Android users.
I decided to pair my Marvels to her iPhone and the app is exactly the same as it is on my Android and there are no new options to do what is described for selecting audio sources within the app. Seems like they messed up the release timing unless it’s smart enough to read the firmware version from the Marvels and enable the options if available. If that’s the case, they should still indicate that in the description. Hopefully it’s a good sign that the new firmware is coming soon to fix the pairing issues with only being able to pair with a single device at a time and the iPhone problems.
