Microsoft 365 OneDrive Android (OxygenOS 13.1) login fails with WebView / Error 2604
On OneDrive Android app, login through Microsoft 365 work / corporate profile fails and always ends up with either blank screen or "No Internet connection" error 2604. Here's the details: Device & Environment: Device: OnePlus 8 Pro (IN2023) OS Version: OxygenOS 13.1 (build IN2023_13.1.0.591(EX01)) Android System WebView Version: 142.0.7444.102 App Affected: OneDrive (latest version from Google Play, 26th Nov 2025) Network: Wi-Fi / Cellular (both tested) VPN/ Private DNS / AdBlockers: Disabled Problem Description: Attempting to log in to OneDrive using a corporate/work Microsoft 365 account: The login screen either shows a blank white screen or fails immediately with Error 2604: “No network”, despite internet connectivity being functional. Logging in with the same credentials in Chrome works, confirming network is not the issue. Issue persists after clearing app data, reinstalling OneDrive, updating Chrome, updating Android System WebView, and ensuring all app permissions and background data settings are correct. Steps to Reproduce: Start with OnePlus 8 Pro (IN2023) running OxygenOS 13.1 Ensure Android System WebView is version 142.0.7444.102 Install latest OneDrive app from Google Play Open OneDrive and attempt to log in with corporate/work Microsoft 365 credentials Observe blank screen or error 2604 Expected Behavior: OneDrive should allow login with corporate Microsoft 365 account Embedded WebView authentication should complete successfully Account token should be saved for ongoing use Additional Notes: Problem appears specific to embedded WebView login on this OS/device combination Likely a systemic issue affecting Microsoft 365 apps relying on WebView for login flows on OxygenOS 13.1 Logging in to a personal outlook.com microsoft account works normally. Hence, it seems to be tied to the WebView failure. Is there any fix to this?
