Vs. BBC Sounds. Long serving R4 fan, mostly on catch up, so iplayer absolutely invaluable. BBC Sounds app launched with fanfare, tried to download it, and augment the experience with podcasts. BUT unable to; requires iOS 11 minimum, when both of my devices are maxed to 10.3.3. But still work fine, not due to be replaced for years hopefully.
The great problem is that time is now ticking for Radio iplayer- it's due to be phased out, Sounds will actually REPLACE it, "in the coming months". The horror 
Is anyone else in same situation? Not sure this is generally realised, and feel that loyal (maturer?) radio listeners are once again going to be sacrificed in BBC's endless drive to interest the "youth" market, and am looking for right of appeal somewhere 
Suggestions? (Please don't suggest replacing iPhone etc, it's totally unacceptable to deplete dwindling resources by needlessly replacing functioning tech even if I had the disposable cash).
