Hi there! I see you’re having trouble with the MyInstants SoundBoard Buttons app not working on your device. To better assist you, could you tell me a bit more about what exactly isn’t working? For example:

- Are the sounds not playing at all?
- Is the app not loading or crashing?
- Is there an issue with specific buttons or features, like ads or uploading sounds?

Knowing these details will help me guide you step-by-step. Meanwhile, since you're on ChromeOS (WebKit engine, version 14541.0.0), let’s start with some basic checks tailored for your setup:

1. Refresh the App or Web Page: Sometimes, sounds don’t play because of temporary glitches. Close the app or browser tab completely, then reopen it and try again.

2. Check Internet Connection: The app relies on internet to stream sounds, so make sure your Wi-Fi or wired connection is stable.

3. Clear Cache and Cookies: Cached data might cause hiccups. In ChromeOS, open Chrome browser, go to Settings > Privacy and security > Clear browsing data, then clear cached images and files.

4. Allow Sound Permissions: Verify that ChromeOS isn’t blocking sound playback for the app or browser. You can check site permissions from the lock icon left of the URL bar.

5. Try Incognito Mode: Open a new Incognito window in Chrome and try accessing the app there. This disables extensions that might interfere with sound playback.

If you've tried these already or the problem persists, let me know the details, and I can walk you through advanced troubleshooting or explore if there are known issues with the app. Thanks for your patience!
