Server Sync Delay: Sometimes, the game server might experience delays in updating the status of items like incense. This can lead to the incense appearing to continue even after its intended duration has passed. Check the time when you activated the incense and compare it to the current time to confirm if it has indeed exceeded 30 minutes.
Solution: Wait for a few minutes and observe if the incense stops on its own as the server catches up. If it doesn't, try restarting the app to force a refresh of game data.
Visual Glitch: There could be a visual bug where the countdown timer for incense doesn't update correctly on your screen. This may give the impression that the incense is still active even when it should have expired.
Solution: Restart the Pokémon Go app to reset the user interface and refresh the correct status of incense. This often resolves visual glitches and brings the game display back in sync with the server.
Network Issues: Poor or unstable network connectivity can cause communication delays between your device and the Pokémon Go servers. This can affect how timely the game receives updates about incense status.
Solution: Ensure you have a stable internet connection. If you're on mobile data, consider switching to a more stable Wi-Fi connection if available. Restarting your device or toggling airplane mode on and off can also help reset your network connection.
Persistent Issues: If the incense continues to appear active well past its 30-minute duration despite trying the above steps, it might indicate a more persistent bug.
Solution: Contact Pokémon Go support through their official channels. Provide details about when you activated the incense, what you're experiencing, and steps you've already taken to troubleshoot. They may be able to investigate further and resolve the issue on their end.
By addressing potential server sync delays, visual glitches, and ensuring stable network connectivity, you can usually resolve issues where Pokémon Go incense doesn't stop as expected due to bugs or network-related issues.
