Hello everyone! Good news! 
The early bird sticker issue has been resolved! You should now be able to fill out your survey without seeing any additional charges. 

Thank you again for your patience, and please let me know if you have any further issues! 

Also, a huge thank you to the BackerKit team for helping me resolve this quickly! 

Appreciate you all!

PS: If you finished your survey, please ensure you double-check it now,  especially if you were an early bird! It  seems that some surveys may be unfinished now due to this issue.
