I changed the wi-fi password on my router (for better security). When I start the iOS app, it goes to the welcome screen. If I try to add a speaker (Play 3 or Beam get 2), the app searches for a long time but doesn’t find them. Clicking on can’t find new product goes to a help screen with suggestions to unplug the speaker, which doesn’t work. The other option is to do a factory reset that I’d like to avoid doing.
If I try to join an existing system, the app tries to log into my network with the old password.
On the Sonos support page, it says that there is an “update existing network” option under System, but I can’t locate it with the new app.
