Hi there! I want to make sure I understand your issue correctly—are you saying that in the Chatium app on your Windows device, you can get online or access the app but your friends are not replying to your messages at all? Or is it that your sent messages themselves are not being delivered or seen by your friends?

Sometimes, this can be a connectivity or settings issue, or it could be about how notifications or message delivery work. Could you share a bit more about what you’re experiencing exactly? For example:

- Are your messages showing as sent or delivered in the app?
- Do you see if your friends are online or active?
- Has this issue just started or been ongoing for a while?

This info will help me guide you better! Meanwhile, I’ll outline some initial checks just in case:

1. Check your internet connection: Make sure your Windows device is connected and stable with Wi-Fi or ethernet.
2. Restart the Chatium app and your device: Sometimes a simple restart can reload everything properly.
3. Verify app permissions: On Windows, ensure Chatium has permission to run and access the network.
4. Try sending a message to a different friend or a test contact to see if anyone gets back to you.
5. Check if the app has any pending updates in the Windows Store.

Does any of this sound familiar or relevant? Let me know more, and we’ll dig deeper together!
