I’m seeing crashes, affecting multiple unrelated apps on my iPhone.
Device / software
- iPhone 12 Pro Max
- iOS 27.0.1
- Robinhood Banking 2.23.1
- Duolingo 7.142.0
- Telegram
- Venmo
- Paypal
Timeline
- I was on a Caribbean cruise Sept. 27–Oct. 2, including Jamaica and the Bahamas.
- I used ship Wi-Fi and different networks while in port.
- Robinhood Banking was still working while I was in the Bahamas.
- The problems started the day I returned, Oct. 2.
- Initially, App Store updates were also hanging.
- Most apps now work normally, but Robinhood Banking and Duolingo continue to fail.
Behavior
- The app opens to the launch/logo screen.
- It remains frozen for roughly 20 seconds.
- iOS eventually terminates the app.
- Robinhood Banking briefly worked after I forced a sign-out and reauthenticated, but the problem returned.
Troubleshooting already performed
- Restarted and force restarted multiple times
- Airplane Mode on/off
- Tested Wi-Fi only and cellular only
- Tested multiple Wi-Fi networks and a separate hotspot
- Changed DNS and returned it to Automatic
- Confirmed no VPN
- Disabled Private Relay and Limit IP Address Tracking
- Checked app/location permissions
- Freed iPhone storage
- Fully deleted and reinstalled affected apps
- Signed out/in where possible
- Reset network settings
- Tried an OTA iOS update, which became stuck on “Update Requested”
- Successfully updated to iOS 27.0.1 through a Windows PC
- Contacted Robinhood and confirmed there is no account restriction
- Removed old Robinhood trusted devices and fully reauthenticated
- Regular Robinhood works normally and my Robinhood card still works
Crash logs are what make this look system-level.
Robinhood Banking repeatedly shows an EXC_CRASH / SIGKILL with a 0x8BADF00D scene-create watchdog timeout after about 20 seconds.
More importantly, its main thread is getting stuck while iOS is trying to create a background NSURLSession and waiting for a synchronous XPC response.
Duolingo is showing essentially the same thing: an EXC_CRASH / SIGKILL with 0x8BADF00D, and its main thread is also getting stuck in the same background NSURLSession/XPC system call.
The watchdog event is slightly different between the two apps, but both unrelated apps are hanging while waiting on the same iOS background networking service.
Because this persists across different networks, app reinstalls, network resets, reauthentication, and even an iOS update through a computer, it doesn’t appear isolated to Robinhood, Duolingo, Wi-Fi, cellular, or DNS.
The cruise may be unrelated, but it is the only major change immediately before this started, involving ship Wi-Fi, roaming, and multiple international networks.
