Visualizations within tooltips applied across all marks, were not properly passing filters when there were multiple fields. The filter would only work against the last field.

The Viz in Tooltip option was not filtering the sheet correctly when a dual-axis was used for the same measure.

On the relationship page, the word "operator" would sometimes be incorrectly translated.

When using page playback, it would sometimes pause and fail to loop.

After upgrading to Tableau Desktop 2021.4, it would be possible to receive an error when publishing or logging into Tableau Server,
"Error Code: 84223ADA
Unable to connect to Tableau Server.
SSLHandshakeException
PKIX path building failed: sun.security.provider.certpath.SunCertPathBuilderException: unable to find valid certification path to requested target."

An intermittent error could occur when accessing a visualization that is connected to a published data source, "No Tableau Server user found. DataServiceFailure."
