Why do your Tinder messages not send?
Have you double checked your internet connection first of all?
If it's definitely not that, then - if you're on an iPhone, try double clicking the home button when you have Tinder open.
You will see a bunch of different windows zoomed out. Hold down the Tinder window, and swipe up.
The window will fly away. At this point just relaunch the Tinder app and try messaging one of your matches.
This always does the trick for me. Hope it works for you too and gets your Tinder app up and running soon!
Your Tinder messages might not be sending because you have an old version of the app.
Just open the app store, go to "updates" and see if there is a new version of Tinder to update.
Once you've installed the Tinder update, try sending a message and see if it will send or not...
