Hi there! I see you're having trouble updating Cooking Diary through the App Store on your device. Just to clarify, you mentioned your device is a Kindle running Android OS 9, but your question references an iOS update issue. Could you please confirm on which device and operating system you're experiencing this? This will help me give you the most accurate guidance.

Meanwhile, if your Kindle is having trouble updating Cooking Diary through the app store (most likely Google Play Store on Kindle), here are some general steps to try:

1. Check your internet connection: Ensure you have a stable Wi-Fi or cellular connection.
2. Free up space: Confirm you have enough storage on your device for the update.
3. Clear cache and data of the store app:
- Go to Settings > Apps > Google Play Store (or the store app you're using).
- Tap Force Stop and then Clear Cache.
- If needed, also tap Clear Data.
4. Restart your device: This can often resolve minor glitches.
5. Try updating again: Open the app store and look for Cooking Diary updates.

Since you're on a Kindle with Android 9, these steps usually help.

If you were referring to an iOS device or the App Store specifically, some additional tips include:
- Checking date and time settings to ensure they are correct.
- Signing out and back into your Apple ID.
- Restarting the device.
- Deleting and reinstalling Cooking Diary while ensuring your game progress is backed up or linked to an account to avoid loss.

Could you please tell me exactly what happens when you try to update? Are you seeing any error messages or does the update button not respond?

That way, I can help you more precisely!

I'm on Amazon fire tablet. When I press Update button in Appstore it doesn't do anything no message.

Thanks for the info! Since you're on an Amazon Fire tablet and the Update button in the Amazon Appstore doesn’t respond, let's try clearing the Appstore’s cache and data to fix any glitches preventing updates. Here’s how to do that step-by-step:

1. Swipe down from the top edge of your Fire tablet screen to open Quick Settings.
2. Tap the Settings gear icon.
3. Go to Apps & Notifications (or just Apps).
4. Select See all apps or Installed Applications to view all apps.
5. Scroll to find and tap on Amazon Appstore.
6. Tap Force Stop to close the app completely.
7. Tap Storage (if visible), then tap Clear Cache.
8. Next, tap Clear Data or Clear Storage. Confirm if prompted.
9. Restart your Fire tablet.
10. After the restart, open the Amazon Appstore again and try pressing Update for Cooking Diary.

If the update still doesn’t start, you might want to uninstall and reinstall Cooking Diary. Before uninstalling, make sure your game progress is saved by linking your account to Facebook, Google, or the game’s cloud save option.

Finally, if these steps don’t help, it's worth noting Mytona (the game developer) has recommended switching to the Google Play version of Cooking Diary on Android devices for best support, but since Fire tablets rely on Amazon Appstore by default, this is a more involved step.

Let me know if clearing the cache and data fixed the problem or if you need guidance on reinstalling or more advanced steps!
