Hello,
Many users includes me have deleted a Dashboard by mistake and then he lost that dash Token forever , user can create a new dashboard
But the problem that maybe this token already hard coded on of your board or a home automation device you’ve created.
Again you have to rewrite the code if you don’t saved you sketch and add the new token , start testing and debugging.
What is needed , to allow the user to retrieve the delete dashboards that assigned to his email ID.
I understand the security concerns that reuse a token maybe lead to it , but you can popup a message to
Explain that to the user and he can accept or reject it.
