At the moment it seems not to work..
I added appr. 250 TB-Codes in 4 or 5 parts for discovery into the tool (Giga-Event in Hamburg) yesterday evening and none of them has been discovered yet.
Also, the queued number of trackables has risen from around 2.500 yesterday to more than 37.500 at this moment...
Is it a problem with the new API? Or is the number of TB's in the queue rising extremely faster than "normal" times?
