I've encountered a similar issue before. Here are a few things you can try:
Check your internet connection: Ensure you have a stable internet connection before attempting wonder trades.
Update the game: Make sure your game is updated to the latest version. Sometimes, bugs are fixed in updates.
Clear cache: Clearing the cache of your game might help. Look for options to clear temporary files or cache in the game settings.
Restart the game or console: Sometimes, a simple restart can resolve glitches. Try restarting both the game and your console.
If the issue persists, it might be a bug in the game. Consider reaching out to the game's support or community forums for more specific assistance. Good luck, and I hope you get it sorted soon!
