Volume randomly stops working

Great app but when the volume randomly stops working, how is that beneficial to a person using it to communicate?

Love the app but updated to iOS 13

So I updated to the latest version of iOS and I'm now experiencing a lot more bugs with snap. Very upsetting.

App Does not open and it crashes

I am an SLP who is always researching and purchasing AAC apps, I had the free version of Snap+Core and was able to use it without technical difficulties last school year. Today as I prepared my lessons, I tried opening it and it crashed, so I updated my IOS to newest version thinking it was on me. Then I deleted the free app and re-installed it and it still crashed. So I decided to purchase the FULL version thinking the free version was defective, and having the FULL version paid for 49.99 in the apple store would guarantee me a functional app. However, the app did not open and it crashed as did the free version.
I really liked this app and have two students I modeled AAC communication on Snap+Core, all my other students are on other AAC apps, I am very disappointed that this AAC app was developed for communication is non-functional even with the FULL PAID VERSION. I welcome the developers to help me solve the problem, and solve this issue for future purchases. I emailed the tech support system, but have not received a response.
