Hi! I understand you're able to log into the 2go Chat app but you can't see any other rooms, is that right? I'd like to help you get this sorted out.

To help me better assist you, could you tell me:
- Are you completely unable to see any chat rooms, or just certain ones?
- Have you ever been able to see rooms before on this device, or is this your first time logging in here?
- Are there any error messages when you try to view or join other rooms?
- Have you tried restarting the app or your device yet?

Assuming you see no rooms at all, here’s a simple step-by-step plan we can try:

1. Check your internet connection: Make sure you are connected to a stable network (Wi-Fi or mobile data). Poor connection can cause room lists not to load.

2. Restart the app: Close 2go Chat completely (remove it from recent apps) and reopen it.

3. Clear cache: On your Android 10 device:
- Go to Settings > Apps > 2go Chat > Storage.
- Tap on "Clear Cache" (not Clear Data to avoid losing your login info).

4. Update the app: Head to Google Play Store and check if there is an update available for 2go Chat. An outdated app might have bugs.

5. Check app permissions: Make sure the app has network access permissions enabled.

6. Check for VPN or proxy: If you're using any VPN or proxy, try disabling it since sometimes these can block access to chat rooms.

7. Try logging out and back in: Sometimes, refreshing your login session helps with loading new data.

If none of these work, there might be a server-side issue or a problem with your account settings. In that case, I can guide you on how to contact 2go official support or escalate the issue.

Let me know what you find or if you've already tried any of these!
