ChrisJ4203, thanks very much for getting back on this. My Linx hearing aids were bought about three years ago, which is why I was particularly disappointed that iOS 11 no longer streamed reliably to them.
It's interesting to learn that your hearing aids may also be the original Linx model. I suppose that there may have been some changes during the lifetime of the Linx model. I'd be very grateful if you could let me know the model number that is reported at Settings/General?Accessibility/MFI hearing devices. My LiNX 3d hearing aids show up as LT961-DRW, for example. My original Linx 9 hearing aids show as LiNX 961. It would be interesting new information if your hearing aids appear to be the same as my Linx hearing aids since that would suggest that I need to revise my analysis!
Thanks again, Brian
