How do we troubleshoot problems with the Android app?

Answer: D — Log out and log back in, clear the cache, uninstall and reinstall the app

The best way to troubleshoot problems with the Android app is to fully log out of the app and clear its cache. If that doesn't work, uninstall and then reinstall the app. option A is too broad as just rebooting may not solve the issue. option B only addresses potential browsing history issues. Option C could be a last resort, but it's more efficient to try the steps in option D first.
