Uninstall the app. Return the speakers. Come back in a few months and ask if it’s safe to buy their products again
Ikea speakers seem to be especially affected - other reports of failure to install are posted here.
Same problem here with a port … . Lost quite some time already trying to fix this problem.
I tried again from an old tablet, and things worked (sort of) - after I stayed up until 3am trying every possible order in which to do things.
However, the only thing that seems to work is SONOS radio. How do I play a file in my collection, say? For that matter, can I use the SONOS speakers from my computer?
I don’t know if there was an update, but after 4 days of trying to add a new sonos port to the new app, it finally worked (before, each time the app crashed).
