### Problem It appears that when I background the Cordova app and use another application on iOS that uses lots of memory, when I return to the Cordova app it shows a white screen and appears to be frozen. There is no way to reload the page or navigate so I’m forced to kill the app and relaunch. Captured the White Screen of Death in the debugger: Here is a short: https://youtube.com/shorts/4rV0T_peIew?si=U60VhrfND7t9yftR <img width="1392" height="897" alt="Image" src="https://github.com/user-attachments/assets/0813b19f-1646-4117-bf74-cd9f7303d61b"; /> ``` CDVWebViewEngine shouldReloadWebView:: CDVWebViewEngine shouldReloadWebView title: Stress-Energy Tensor Inquiry - Ozwell CDVWebViewEngine shouldReloadWebView location: http://localhost:12992/session/sjrSNPmbYmHHkyAvb CDVWebViewEngine shouldReloadWebView reload: 0 Clock discrepancy detected.

We fixed it in our code, but using the override and fixing it to reload when the title is null or empty. This has fixed the issue. We are making a PR to make sure this is fixed for everyone. I think this is an Apple bug, but Cordova is severely unstable for those that get into low memory conditions on their phone… Isn't that everyone?
