You should be able to reply most of IM messages directly from the pop-up notifications! However, if you cannot see the "Quick Reply" button from pop up notifications or the pop-ups just don't show, it might be your setting issue, some adjustments needed.
How to enable Desktop Notification?
1. Make sure you can receive the notification of the apps on your phone first.
2. Turn On the permission of Desktop notification on your device.
Open AirDroid App> Me > Security & Remote Features > Desktop Notif. > Enable Permissions
However, the reason for the issues regarding Quick Reply might be caused by your Android version:
- If you still have the problem in replying to WhatsApp/Skype/Line messages:
Make sure your Android device is running 4.4+ for Whatsapp; for Skype 5.0+ and Line 4.4.
- If you still have the problem in replying to Kik/Telegram messages:
Please make sure your Android device is running 4.4+
Note: If your Android device is running 4.4.2/4.4.3/4.4.4, when you get a notification pop-up includes more than 2 messages, you can't reply to this message. Please read those messages on your device first.
e.g. There are 2 messages in the first pop-up, and you can't reply to this message (This issue doesn't happen to devices running Android 5.0+)
