When registering your device in Thingsee Creator you might be prompted with the message "Couldn't register device" in Step 2 of 3 like the picture below.
This is a problem in our cloud provider and we are aware of it. Please do not try to register again because the device will still be added and you'll end up with as many devices as the times you pressed "Next". Something like the picture below! :) Please delete all the extra devices registered and wait for our update.
We are investigating and will try to solve it as soon as possible.
We're sorry for the inconvenience that this might cause you and we kindly ask for your understanding.
