I can't complete the Story mode in GW2

I'm sorry to hear that you're experiencing difficulties completing the Story mode in Plants vs. Zombies Garden Warfare 2. I can offer some general suggestions that may help you troubleshoot the issue:

• Verify game updates: Ensure that your game is up to date with the latest patches and updates. Sometimes, game updates can fix bugs or glitches that affect story progression.
• Restart the game: Try restarting the game and reloading your save file to see if it resolves the issue. This can help refresh the game's state and potentially resolve any temporary glitches.
• Replay previous missions: If the game is not registering that you have unlocked the new portal, try replaying the previous missions or completing any outstanding objectives. Sometimes, completing certain tasks or missions can trigger the progression to the next stage of the story.
• Check for any missing requirements: Double-check if there are any specific requirements or conditions that need to be met before unlocking the new portal. It's possible that there is a specific task or objective you need to complete first.
• Contact support: If the issue persists and none of the above steps resolve it, you may need to reach out to the game's official support channels for further assistance. They will have access to more specific troubleshooting steps and may be able to provide a solution or workaround for your particular issue.
• Remember, it's always a good idea to provide as much detail as possible when contacting support, including the platform you're playing on, any error messages received, and a description of the issue you're facing. This will help them better understand and address your problem.

I hope these suggestions help you resolve the issue and allow you to complete the Story mode in Plants vs. Zombies Garden Warfare 2. Good luck!
