Problem: In projects with chained datasets, attribute filters may not work correctly, causing problems with Mapped/Unmapped attributes in downstream projects.

Releases affected: 2019.023.1 and greater

Release fixed: v2021.021

Resolution: If you encounter this issue, contact Tamr Support for information about a workaround, which involves running an internal-only API request to calculate attribute mappings.
