Hey MV4Si,
I can understand confirming which items are new is very challenging with this issue, but the contents are absolutely being delivered to your account.
In your own video from an earlier post, you can see this most clearly by just keeping an eye on your Crafting Materials in the lobby. You have 345 prior to opening the packs, and even after the errors, have 1.46k on returning to the lobby.
The contents are being delivered, the new item notifications just do not appear in these situations. Thanks for the patience while we're looking into this.
