Additional Information: iPhoneSE(Generation unknown - details from client) running iOS 26.0.1: The WebSocket disconnection issue did not occur. Any iPad running iPadOS 26.0.1: I wanted to test this, but I couldn't perform the verification as I didn't have a corresponding device on hand. iPad(A16) running iPadOS 26.2: When accessing directly via the Chrome browser, the WebSocket remained stable and did not disconnect. However, the issue was reproducible when using the PWA version (installed via Chrome). (Does the PWA use the Safari/WebKit engine internally even when installed through Chrome?) Additionally, I found logs corresponding to the time of the occurrence under Settings > Privacy & Security > Analytics & Improvements > Analytics Data. I am attaching those files to this post for reference.
