Why are my apps not working?
The problem has been traced back to the Android System WebView.
System WebView - which is what apps use to display web content such as in-app web browsers - comes pre-installed on all Android phones.
Android users have flocked to social media to discuss the app issues they're facing and to try and find a fix.
Google have said today that they are aware on the issue - and are working on a fix.
