Just a brief recap.
My GN Resound Linx 9 hearing aids don’t stream reliably to my iPhone 8 and also had problems streaming to my previous iPhone 6 when I upgraded it to iOS 11.
It looked as if the root of the issue was iOS 11 since the hearing aids still streamed perfectly to an old iPhone 5 running iOS 10.
My High Street audiologist was sympathetic and checked with GN, the hearing aid manufacturer, but got no useful advice from them.
I reported several suspected bugs to Apple, along with bluetooth logs giving Apple detailed diagnostics.
I also made contact with a GN ambassador who suggested that Apple had withdrawn support for earlier model hearing aids and that current GN models stream fine.
Well, I’ve tested this by getting a pair of GN’s latest Resound Linx 3d hearing aids on 30 day trial and yes, they stream nearly perfectly to my iPhone 8. Phone calls are reliably streamed to both ears and I can stream talking books and the signal from VoiceOver, the speaking interface for blind iPhone users.
Very occasionally, sound is streamed to one ear only, but this is fixed by turning bluetooth off and then back on. This is hugely better than the streaming performance I had with the earlier model Resound Linx 9 hearing aids.
So this certainly seemed to support the conjecture that Apple had indeed dropped support for older hearing aid models. I decided to email Apple Support and seek clarification. Apple’s reply and my email are copied below.
In summary, Apple state that
the impact of iOS 11 on streaming performance was not intentional, that they are aware of the issue and that they can give no date for a fix being available. I’m guessing that it could be a very long wait - it already has been. Some of you seem to be having streaming problems with current model hearing aids and I’d certainly suggest that you follow these up with your audiologist. But those of us with older hearing aids that stopped streaming properly with iOS 11 may have to consider replacing the hearing aids or purchasing a streamer. There’s more about streamers in my other posts on this subject.
The main snag with streamers is that they are slower to establish a connection between the phone and hearing aids than a direct connection and, of course, you have to wear the streamer clipped to your clothing. However, a streamer is likely to be cheaper than a hearing aid replacement. I’d say that it’s very unlikely indeed that the solution for older hearing aids will come from the hearing aid manufacturer; the fix must come from Apple.
However, if you have problems with a current model hearing aid then the problem may well be with the hearing aid since at least one model, the Resound Linx 3d, seems to work fine. My correspondence with Apple support follows.

Hello Brian,
Thank you for your email. We’re glad to know that the trial pair of ReSound Linx 3d hearing aids is going well, and that you are not experiencing any problems with streaming.
To our knowledge, support has not been removed for any Made for iPhone Hearing Aids devices. The issues that you were encountering with your previous hearing aids are not expected, and are currently under investigation. We cannot comment on when they may be resolved.
Sincerely,
Apple Accessibility

>Hi, I've previously submitted some suspected bug reports relating to unacceptably unreliable streaming from my Apple iPhone 8 to my GN Resound Linx 9 hearing aids. Streaming, is slow to establish, often to one ear only and frequently fails completely and reverts to the iPhone speaker. Apple's forum on MFi hearing aids suggests that users of hearing aids from other manufacturers are experiencing similar problems with iOS 11. (I was previously using an iPhone 6 with iOS 10 and all worked fine.)

This may have been unintentional, but it certainly does seem that iOS 11 is very poor at supporting streaming to older MFi hearing aids.
