An interesting issue currently exists in the App for Explorer benefits at the moment. This was acknowledged by the agent at the Swisshotel, Singapore during my stay over Christmas.
It concerns the Welcome Drink benefit.
Long story..... As is my usual procedure, I almost always book a room as early as possible when planning any trip. I will then check back about a month out to see what rates are then available. Sometimes the rates are higher but often, they have been reduced. In the case of the SIN booking, quite considerably and, in fact, a Stay Plus night was available when originally this was not offered. The saving was considerable. So I booked and prepaid about a month out.
However the App still believed I had an existing booking (even though cancelled) for the same dates so did not offer the Welcome Drink on the new booking. The same happened, for the same reason, with a Hong Kong booking two days later. In both cases, a paper version of a Welcome Drink was provided without further discussion. In fact, in the case of the Swisshotel, I probably got a better drink than the App may have offered.
Not sure if anyone else has had this issue. I understand it has been reported to Accor.
