My Note 3 Forced Me To Restart And Uninstall The Drizzle Sms App. And Thoughts?

Hello,I installed the Drizzle SMS app two days ago and loved it. But it temporarily broke my phone. I kept getting a message saying, "Drizzle SMS is sending a large number of texts. Do you want to allow this?" It would not let me allow it. Or deny it for that matter, and it did not allow me to use any function of my phone while the message was displayed. I had to restart my phone. It happened again, so I uninstalled the app. I really liked the app though. Any thoughts on how to fix this so I can safely reinstall Drizzle SMS?Thank you!Liam Hirst-Graves
