No, it’s working okay here. As a first suggestion, is the device you’re using perhaps short on storage space?

No it’s running a beta system I suspect that to be the reason. I just tried it on my work phone and it works fine. 

Ah yes, the Sonos Apps (and other Apps) are not guaranteed to work with any beta operating systems. I think others have mentioned that it is not working with iOS beta v17.4, for example, so that’s ‘likely’ the cause of your issue. 

See this thread, which perhaps may assist too…
