Whatsapp App Not Opening On Mac Os Force quit the app, then open it again Same issue - torn my little remaining hair out. Deleting the app takes it back to 'waiting' - VERY belatedly upgraded my IoS to 6 from 5 - downloaded Whatsapp update from macbook and tried to install it from there. It starts to install it but then gets stuck on install.
Logged out and in of the app store - taken the app off and on via iTunes. If the app is crashing, you can’t send messages. There are a few possible reasons why WhatsApp is not working on your Android device.Thankfully, all of them can be fixed relatively quickly. But over recent months, an increasing number of questions are being raised. Consumer-friendly and encrypted, WhatsApp is one of the most popular apps in use today with a whopping 1.5 billion users. Once this is done, select the Delete app option twice in a row on the screen that appears, so that you can uninstall all the app data. Start the latter by using the gear icon on the home screen and select General iPhone Free Space WhatsApp.
Now uninstall the app via the iOS Settings panel.
