There will be cases where you will experience a delay in receiving a response from your guide. Please do not take it personally, your guide may just be extremely occupied or currently in an environment where internet connection is not available.
In such cases, give them some time and wait; In many instances, your guide simply missed the notification for an incoming message, so send them a message or two to notify them further. However, we cannot simply rule out the possibility where the guides may be too occupied with their life; making them unable to perform TOMODACHI GUIDE-related activities. In an event where it happens, giving up is probably your best option. We have plenty of other guides currently using our platform, so start your search once again!
