Hi Power-Up developers!
There will be a small change to the functionality of the Remove Personal Settings button starting by the end of this week. Previously, when a user clicked this button on a Power-Up’s settings menu, the private data stored on board, organization, and member scopes were deleted. Going forward, we will now also be deleting the private data stored on card scopes for active and archived cards on the board in order to be more comprehensive and consistent with the way we handle user data. No other change will be made to the Remove Personal Settings functionality or the remove-data capability.
Thanks for all your efforts making Trello awesome, and thank you in advance for your understanding!
