Hi there! I understand that your messages on the Nayo app aren’t sending immediately, and you'd like to troubleshoot that. Just to get a better idea, are the delays happening all the time or just occasionally? Also, is it only in the Nayo app or other messaging apps as well?

Meanwhile, here are some initial steps we can try specifically for your Android 10 device and the WebKit browser environment:

1. Check Internet Connection: Make sure your device has a steady internet connection, whether Wi-Fi or mobile data. Sometimes intermittent connectivity slows down message sending.

2. Allow Background Activity for Nayo App: Android can restrict apps from running in the background, which can delay sending messages.
- Go to Settings > Apps & notifications > See all apps > Nayo
- Tap on Battery > Disable “Battery Optimization” or allow background activity for Nayo.

3. Clear Cache of the Nayo App: Cached data can sometimes cause delays.
- Settings > Apps & notifications > Nayo > Storage & cache > Clear Cache.

4. Update Nayo App: Ensure the Nayo app is updated to the latest version from Google Play Store, as updates often have bug fixes for messaging issues.

5. Restart Your Device: A quick reboot can resolve temporary glitches affecting app behavior.

If you have already tried these or if the problem continues, please let me know. We can then look into deeper fixes, like checking your account subscription status on Nayo or app-specific permissions.

Are you able to try these steps and tell me how it goes?
