Thanks for the reply, i was quite sure it would be that way, which means that you are just losing a customer.
I do not wish to be required to have my cellphone or my mail on hand when trying to connect to the app or to this forum. I would have liked, though, to find information on the website on how to determine why i would not receive notifications when i’m in front of the camera, or to be able to contact the firm by mail while the only one accessible link on the french site leads to a dead end.
