Hi there! I understand you're having trouble entering your CVV code when trying to make a purchase on the BJ's Wholesale Club app using your Kindle device. Let's work together to get this sorted out.

A quick check for me: Are you able to enter other card details like the card number and expiration date without issues? Also, is the CVV field not responding when you tap on it, or is it something else happening?

Meanwhile, here's a step-by-step process to try:

1. Restart the App: Close the BJ's app completely and reopen it. Sometimes, temporary glitches clear up with a fresh app start.

2. Clear App Cache: Since you're on Android OS 5.1.1 on your Kindle, clearing the app cache can help. To do this:
- Go to Settings > Apps > BJ's Wholesale Club.
- Tap Storage, then tap Clear Cache.
- Reopen the app and try entering the CVV again.

3. Check Keyboard Input: Sometimes the keyboard might not pop up correctly on older Android versions. Tap on the CVV entry field and make sure the keyboard appears. If it doesn't:
- Try switching to a different keyboard app temporarily in your device settings.
- Alternatively, tap the field a couple of times to prompt the keyboard.

4. Update the App: Make sure your BJ's app is updated to the latest available version compatible with your device. Older app versions can cause input issues.

5. Try Alternative Payment Method: If possible, try adding another payment method or use ExpressPay within the app to speed checkout without needing the CVV entry manually1.

If these steps don’t help, it’s possible there could be a compatibility issue between the BJ’s app and your device’s OS version, or a specific bug affecting CVV entry. In that case, contacting BJ's customer support at [email protected] could provide a solution tailored to your account and device3.

Let me know how this goes, or if you notice anything specific when you try to enter the CVV code! Are you satisfied with the solution I provided?
