Hi @Anna-Sophia_Schmidt, thanks for flagging this!
In this case, I suggest reaching out to our Support Team with the following information of one your deleted items:
- Task name and URL (tip: you may be able to find the URL in a previous email notification)
- Project name and URL where the task was located
- Team within which the task/project was located
As our Support team has access to additional tools that we don’t have here on the Community team, they will be able to look into this further for you.
