The app is really annoying due to its frequent updates. Each update is more than 60mb. The app itself is useful but it uses a lot of data. It also drain my mobile battery lot more than useual. So I uninstall it and install the fb lite app. It takes huge anmout of my mobile RAM and storage. But the worst part is this app itself doesn’t give us the messenger option. You have to download another resource hungry app Messenger for that. Please do not install it. Use your browser for FB or the FB Lite app.
