This is too be expected, the thing I noticed all through your post was how your putting far to much into this “remote” support then you need to, and this from a new user is a little concerning,
because if you’d done the “research” with your backdoor training you’d have picked up that it’s not Plug and a Play for most people, it can actually be a work in progress for a lot of us.
Yeah that’s the beauty of the manufacturer’s software, it’s all pretty easy enough to do, you can DIY better then you realise, the biggest problem I see with your approach that only “remote support” can possibly fit your HAs is the feedback test and any REM can’t be be done (not that I’m a great believer in REM anyway) especially with Compass.
You’ve also mentioned a remote tuner, never heard of it,what is it? Or do you mean the Noahlink wireless programming device, if so a brilliant choice,this way you can totally program your HAs as DIY project and get the best from your HAs, all from the comfort of your home! remember only you know what your hearing and how you like things to sound, “no-one” else can possibly know this.
