I have an OM5 I'm using with an iPhone 13 pro.  When using the Mimo app it will not recognize my Rode VideoMic Pro + microphone?  It just ignores it and uses the iPhone mic.  The Rode works fine automatically with the Apple photo app.  How can I fix this?

Return the OM5 and buy an OM4

I think I figured it out.  You have to set the phone on mono (not stereo) and it works fine with this mic (which is mono).  Apple app sets it automatically, Mimo does not.
