Luckily I ordered two, because one does not work. The other works properly once you have found the right app, because the name in the otherwise pleasingly good instruction in neat English is not clear. You have to follow the picture and ignore the description in the Play Store. Since the second one is missing, the first one has to take on a different role. Unfortunately, I have not been able to rename it so far, but there is no possibility of confusion either.
Ok
