In a previous post pokeutopia says that he has Quattro v7 UP receivers. I see from a previous post of yours, you have Quattro 9’s and from your audiogram, perhaps you have UP receivers, too. Another thought would be are your device BTE or RIC (don’t even know if Quattro’s come in BTE - air tube - form factor).
I got a generic reply from ReSound Consumer Help that basically sounds like the rep really has no idea what might be going on but the rep says that there can be differences between USA and UK (although that’s not what’s going on here per David Hendon’s report from over the pond) and the rep also ventures that maybe it could have something to do with the age of the Smart 3D app (I have the latest for both iOS and Android so I doubt that has anything to do with it-one would think a OTA firmware update would advertise the need for a new version of the smartphone app, etc.). Another thought would be that the firmware difference has something to do with a CI but neither you nor pokeutopia mention such that I could tell from skimming over your posts. Since my Quattro’s are workin pretty well for me, I ain’t gonna worry about no firmware updates!
