Hi there! I'm here to help you with the invalid login issue you're facing on the OTC Network app. Let's figure out what's going on so you can check your balance and use the price scanner.

To get started, could you let me know if you're using the correct login credentials, including your registered email and password? Additionally, have you recently changed your password or tried resetting it?

If you're unsure about your password, a good step would be to attempt a password reset through the app.

Here’s how you can do that:
1. Open the OTC Network app.
2. Tap on “Forgot Password?”
3. Follow the prompts to reset your password via the email associated with your account.

After doing that, try logging in again. Please let me know if that helps or if you see any specific error messages!
