Audio alert Issues

I have a Samsung SM-J320A phone. Bought a Stick Up Cam and got it set up. I chose the Dogs alert and tested it out and it worked fine, for about 5 minutes. I called 3 different times and was bumped up to “advanced tech suppport” the last call. I have deleted the app, reinstalled it and while we can get it to work after all that, the audio alert telling me that I have somebody on my porch, won’t sound off. Any suggestions? Thanks Greg
