There were very legitimate concerns about no information or, worse still, misleading information coming from the club during the close season and the very beginning of this.
However, under the new chairman, the club has gone a long way to remedy that and, frankly, I wouldn't be getting too het up about a delay in officially posting details of a friendly match arranged at short notice which will involve fringe players and is not even being hosted by the club.
As has been said, the details of the match are widely known from other sources, I honestly don't know why you seem so exercised by the matter.
