Even as the day was coming to a close in the East Coast of the U.S., DownDetector noted that Gmail was experiencing a problem
Tap on the three dot menu and you’ll see a rectangle that you’ll need to tap to remove all updates from WebView
Even at 11 pm EDT, DownDetector was showing that apps like Google Search, Gmail, the Google Play Store and others were still experiencing problems. Uninstalling the Android System WebView appears to be your best bet at getting these apps to work right for the moment. To to this, go to Settings > Apps & notifications > App info > Android System WebView. Tap the three dot menu button in the upper right corner. That will reveal a rectangle that says Uninstall updates. Click on it and you’ll be asked if you want to replace this app with the factory version. Answer “OK.” And that should stop your Android apps from crashing.
