It isn't a feeling hassled issue, it's more of a being in the tech world over 20 years and seeing manufacturers take shortcuts because doing things properly would take too much effort. It never stops.
I am interested in the fact that you said you can plug a USB drive and get the .ady file that way. That should be documented and the app should 100% be able to do this without the effort of plugging in a USB drive and transferring files to my phone/tablet.
When I first used the app it was 100% garbage. It wouldn't work properly on multiple devices of mine. When the updated it to get the bugs out, it works great now.
Companies rush incomplete products to market, including apps, and it's annoying.
Unfortunately, I no longer work in the Complaints Department— so while I can't solve your complaint, I can totally empathize with your frustrations. I feel them, too.
I've spent days monkeying with a USB drive that had my 4400H Denon AVR config saved to it. I couldn't decode the garbled text.... I admit I was expecting an xml file, but it was output of compiled code and inscrutable to mere humans.
I was able to take an ".ady" file from my tablet, pull it in to that not-fully baked GitHub project called Ratbudyssey, and could modify the file and then upload to my AVR.
I then saved the edited AVR config to the AVR, and then backup the setup file to USB... but it was still garbled text.
So I'll return to my old ways, saving variants of the multiEQ app output, and settle back into my watch-cry from Into the Woods: "I wish the cow was full of milk, I wish the walls were full of gold, I wish a lot of things!" It always brings me back to "no one is alone".
I will never ask you to refrain from voicing what you frustration, I'll keep my grease away from your squeaking wheel. That squeak causes change for the rest of us.
It's in these forums that manufacturers realize the effects their products have on us, and the crap we wade through daily using their stuff. It will be a bit before manufacturers realize what we already love about our powerful mobile devices: the power we derive as a result.
