Hi there! I understand you're having trouble placing trees and finishing the tutorial in Voidpet Garden on your iPad. Let's see if we can get this sorted out together!

First, could you tell me if you're encountering any specific error messages when trying to place the trees, or is it just that the action doesn't seem to register? Also, have you confirmed that your game is updated to the latest version available in the App Store?

In the meantime, here are a few preliminary steps you might try:

1. Check for Game Updates: Open the App Store, go to the "Updates" section, and see if there's a new version of Voidpet Garden available. If there is, install it.

2. Clear App Cache: Sometimes clearing the cache can help. You can do this by double-clicking the Home button (or swiping up from the bottom of the screen if your iPad doesn’t have a Home button) to bring up the multitasking view, swiping the Voidpet app off the screen to close it, and then restarting it.

3. Restart Your Device: You've mentioned you've rebooted your device, but sometimes a hard restart can help. Press and hold the Power and Home buttons simultaneously until you see the Apple logo.

If you've already tried these suggestions, I can check more specific solutions that have worked for other users encountering similar issues. For instance, some players have reported needing to re-attempt certain tutorial actions or even starting fresh if they got stuck.

Let me know how it goes, and we'll work from there!
