Once again (a few months after my original post) iPlayer has stopped working on my 4K Express HD player. BBC support has confirmed that the 3940EU is not a supported model and they can't help me. But this model is still on sale and widely advertised (for example by Argos) as working with iPlayer. (I can't see the model number on their advert but from the pictures it's identical to mine.) I think this is misleading advertising, and although my device is out of guaranteee by a few months I'm going to see if they will refund or replace.
However the lack of other posts on this topic rather indicates that most people's 4K Express HD devices are still working with iPlayer so I think it might be only mine. And it didn't suddenly stop working. First streaming kept having glitches, then the iPlayer app got slower and slower to load, and finally it won't load at all beyond the opening splash screen. But other channels that I've tried have no problems at all. Seems very odd to me, anyone got any ideas? It is definitely not an internet connection or power supply problem, those have been thoroughly checked out.
