Hi

I believe there has recently been a problem with the WhatsApp service that is unconnected to Firefox for Android. I recommend trying WhatsApp again in a day or so.

So what can I do

I would recomend that you contact the WhatsApp support team for help with this issue.

How to update ?

Hi

You can make sure that Firefox for Android is up to date by opening the Google Play Store app on your device and checking for any application updates to the apps that you have installed.
