I don’t get a prompt to install the app.
Sometimes it may take a few seconds for the prompt to show up due to server load or internet speeds.
So, just be patient. If you have been waiting for more than a minute try restarting Ignition.
If that doesn’t work, try a new internet connection and try again.
Finally, if all else fails, send us a Direct Message on Twitter @ignition and we will try help you solve the problem.
