SOLUTION

To provide an active demo/guest account or a valid username and password for reviewers to access your app, follow these steps:

Step 1: Create a Demo/Guest Account
Create a specific demo account that the reviewers can use. Make sure this account has sufficient permissions to access all the features of your app.

Step 2: Ensure the Demo Account is Active
Ensure that the demo account is always active and can be accessed without any issues. Test the account yourself to verify that it works correctly.

Step 3: Provide Credentials in the Play Console
Go to the Play Console: Log in to your Google Play Console.
Select Your App: Choose the app for which you are providing the demo account.
App Content: Navigate to the "App Content" section in the left-hand menu.
App Access: Click on "App Access."
Add Instructions: Add instructions for the reviewers to access your app. This should include:

Username
Password

Any special instructions needed to log in (e.g., if they need to bypass any screens or use specific buttons).
Here is an example of how to fill out this section:

Example:

Username: demo@example.com
Password: demo1234

Step 4: Provide Detailed Instructions
If your app requires additional steps to access the content, such as selecting options or navigating through certain screens, provide these instructions in the "App Access" section. Here’s an example:

Instructions:
Open the app.
On the login screen, enter the following credentials:

Username: demo@example.com
Password: demo1234

Click "Login."
If the app navigates to a welcome screen, click "Continue" to access the main features.
Step 5: Test the Credentials
Before submitting the credentials to Google Play Console, test them yourself to ensure they work from different locations and devices.

Step 6: Resubmit Your App for Review
After providing the credentials, resubmit your app for review. Here’s a brief recap of what you should provide in the Play Console:
