Hi @arteny, thanks for reporting this.

I've confirmed the bug. When RemoveByTagAsync is called, it correctly deletes all the data keys referenced by the tag, but it never deletes the tag Set key itself (tag:{tagName}). This means every tag that has ever been used persists in Redis as an empty Set, effectively a slow memory leak.

A fix is on the way and will be included in a release later today.
