Update: This issue is fixed.
We’ve received bug reports today about users creating a new account, but not being able to save their brand new packs. Upon pressing the Save All button, an “incoherent data” error was appearing.
I do not have more details yet as to the cause of the error, but I’ve been told that the bug has been identified and the fix is being tested before going live.
If you have encountered this error and would like to be notified when it has been fully fixed, please open a support ticket here and I will contact you once you can begin using your new account.
Sorry for the hassle folks. We’ll get you up and running as soon as possible.
