Sorry to hear that. I have yet to get my invite, although I'm actually somewhat relieved that I didn't get one this week because I've been away for most of the 'qualifying period' and I wouldn't have been able to use the pass had it been for my hometown. Another player on my Discord said that he didn't get a pass after his Sprint EX on Christmas was cancelled (one that was accessible and he was going to do it), so Niantic royally screwed over those players.
I had hoped the hiatus meant they were reworking things, but that was misplaced it seems.
