Hi there! I'm here to help you with the issue of not being able to see your profile or send messages on FET. Let's troubleshoot this together.

1. Check Your Internet Connection: Ensure that your device is connected to the internet. You could try opening a different website or app to confirm.

2. Log Out and Log Back In: Sometimes simply logging out of your account and then logging back in can refresh your session. If you haven’t tried this yet, please do.

3. Clear App Cache: Since you're using an Android device, clearing the cache can often resolve issues. Here's how to do it:
- Go to Settings on your phone.
- Scroll down and select Apps or Application Manager.
- Find and select FET from the list.
- Tap on Storage and then select Clear Cache.

4. Update the App: Make sure that you have the latest version of the FET app installed. You can check for updates in the Google Play Store.

5. Reinstall the App: If clearing the cache doesn't work, you may need to uninstall the app and then reinstall it from the Google Play Store.

If you've already tried some of these steps, please let me know which ones so we can find a better solution together. Are you also receiving any error messages when trying to access your profile or send messages? Your input will really help me assist you better!
