No, once an activity has been archived, it cannot be unarchived or reused.
When a shared activity is archived, the associated funds are automatically returned to the main budget. The original activity becomes inactive and cannot be reassigned or reactivated by another user.
What You Can Do Instead
If you need access to those funds, you can:
- Create a new activity from the same main budget.
- Or ask the owner of the budget to create and assign a new activity to you.
This ensures that funds are properly allocated and tracked under current, active users.
