How do I update my Android Webview system after redownloading it from the webview regression?

To update Android System WebView again after reverting it (factory mode) and fix issues from the regression, follow the sequence that has been confirmed to work:

1. Open Settings on the Android device.
2. In Settings, use the search box and search for "Android System WebView".
3. Select Android System WebView and then choose App details in store (this opens its page in Google Play Store or the device’s app store).
4. In the store page, first Remove/Uninstall updates so WebView is fully reset.
5. Reboot the device.
6. After reboot, go back to Settings → search for "Android System WebView" → App details in store.
7. On the store page, tap Update to download and install the latest WebView version.
8. Reboot again if prompted, then open affected apps (for example Outlook or Teams) and sign in.

If Android System WebView does not appear when searching in Settings:

1. Go to Settings → Google → All services → System services.
2. Select Android System WebView from that list.
3. Use App details in store from there, then follow the same steps: remove updates → reboot → open App details in store → update.

This process takes WebView out of the outdated/factory state and brings it back to the current release, which resolves the regression-related issues.
