Nothing to add other than: i have the same issue. Also tried with a new Tuya account to be sure, no success. In the [App][Tuya] part of the forum there was another user with the same issue. So i assume this is something systematic?
Therefore the post is moved into the appropriate topic, closed and will be automatically deleted in 7 days to keep the forum clean as possible. If you have any problems with that please feel free to contact me or another moderator.
