When I open the Sonos app on a recently factory reset iPhone, and try to log in, it redirects me to the login.sonos.com website but I get a blank white screen. On the same phone if I go directly to the Sonos.com website and try to login I get the same blank white screen. I tried in Safari and Chrome cleared my cache, tried private browsing, turned off about 15 other security settings that I could think of. And nothing seems to work. Of course it works fine on my Android phone using Chrome browser.
When it is being redirected a small letter I with a circle around it pops up or have a second so I'm sure there's still some security issue but the heck if I can figure out what it is. It is an older iPhone for whatever that is worth.
Technical details. Thing I have tried:
-Verified JavaScript is Enabled in Safari Advanced settings.
-Cleared Safari History and Website Data to remove corrupted cookies.
- Attempted login via Chrome (including Incognito mode) with the same blank screen result.
- connected to different Wi-Fi network
- Uninstalled and reinstalled the Sonos app multiple times.
-limit IP Address Tracking.
- toggled Private Wi-Fi Address OFF for the local network.
Attempted to bypass the redirect by using "Request Desktop Website" in the mobile browser.
Modified DNS settings to Manual (Google DNS 8.8.8.8) to rule out router-level filtering.
Attempted login in both Light and Dark modes to rule out UI rendering bugs
Typed the login URL directly into the browser instead of trying the redirect
