Oof, you might want to take a look at some sources.
First, the US Supreme Court has issued no order on mail-in ballots, but rather denied an order to block the counting of undated mail-in ballots. Later, they threw out a 3rd circuit ruling that said undated mail-in ballots must be counted. However, throwing out the 3rd circuit ruling was only to prevent it from becoming a precedent in the other states where the 3rd circuit resides over.

Second, it was the Pennsylvania Supreme Court, not the US Supreme Court, that finally clarified the status of undated mail-in ballots, and that they must be segregated and left uncounted.

John Fetterman has sued the court, again citing the same reasons as the 3rd Circuit Court’s decision to allow undated ballots. It has yet to be determined what will come from that, but as it stands, aside from arguing that the undated ballots should be counted, I’ve found no evidence that they have been. Nor anyone claiming that have.
Mind citing your sources or are your facts based on your opinion?
It would explain your confusion of the US Supreme Court and the Pennsylvania Supreme Court ruling.
Next time, check your facts before being snarky.
