When the end date for an exchange passes, the People Like Us system will automatically change an exchange from Finalised to Completed. Once Completed, you can leave feedback for your exchange partner and their home. If you can't see the button, then check the following: - Is the exchange finalised? If not finalised, it won't change to Completed. - Did you add dates? It's not mandatory to add the second leg dates but, if you don't, the system won't know that it's complete. - Is your part of the exchange complete? You can only provide feedback once your side of the exchange has completed. For simultaneous, both sides complete at the same time but for non-simultaneous, you can only add feedback after you have travelled.
