App trouble recognizing Low E, partial solution

Howdy all. I’m a 2month old newbie to (acoustic) guitar/JustinGuitar

In the app it has a very hard time recognizing the low E tone.
I noticed that if I play it very lightly, it picks it up faster. Maybe too many overtones for the mic on the old iPad mini?

Also noticed that it has trouble recognizing the D string on the Yamaha I’m using. It’s in tune (at least according to the TC Electronics Unitune). I found if I tune it just a shade sharp, it picks it up faster.

I’m guessing this has to do with the harmonics of this particular guitar X capabilities of the iPad mic X the software module looking for a certain note.
