I know this shouldn't surprise anyone since it's EA, but I don't think I've seen a season launch go so awry.
Issues I've experienced that I've seen others mention as well:
We usually get a load of duplicate packs when the new season goes live (packs earned from previous season objectives). While those did pop up when I logged in, they are not showing visible as a pack to open. Instead, I only got a stadium pack and a random 94+ Mirage pack and a bunch of alumni tokens. However, it says I still have 18 unopened packs. In the popup, I saw the What If and Gamechangers packs that I was expecting. I'm assuming those are most of the phantom 18 packs I have "unopened" but cannot access. I've never seen a season not work properly in that regard.
We always have a set of weeklies and a set of milestones that refresh every week. Currently, there is only a set of weeklies (granted there was a past season that in the final week they didn't refresh one of the two so some people who didn't have the premium pass missed out on earning the final tiers). EDIT: Milestones are in the dailies tab as their own section lol
