I am wondering if your "Notifications for Gear S" app will allow me to respond to group messages. Currently with the stock message app on my watch I can only respond to the last person in the group. Please let me know.
The app only provides notifications. It doesn't have support to reply to group messages. If you check the application's page at Play Store, you'll see that other users reported this issue. The software is having issues with group messages and group notifications from WhatsApp.
I see the app is not free, but I recommend contacting the developer to ask him about this and then buy it if it suits you needs, but in current state, it has issues with group messages.
