Good news: streaks worked perfectly this morning.
Bad news: outside of the packs granted by the streak, I’ve accumulated three packs in the last 23 hours. That’s horrendous.
UPDATE: this is weird, but: Packs are working! The COUNTER continues to show zero available, but if I know I should have some, I can go to the pack, click “get packs” and open the usual number. Go figure.
