As Ludwig AI indicates, this phrase is grammatically correct and widely used in writing, particularly in news, scientific, and academic contexts. While highly versatile, "have still not" can sometimes come across as overly negative or accusatory if overused. Therefore, writers should consider alternative phrases such as ""have not yet"", ""still haven't"", or ""have yet to"" to achieve a more balanced tone, as needed.
