Valorant Battle Pass Not Unlocking: How to Fix
By Andrew Lin

Valorant battle pass not unlocking might be giving you trouble if you've purchased the premium battle pass.
Some players have reported that despite completing a tier on the battle pass, they don't get the associated reward. The same issue has also been reported for mission rewards. More egregiously, players are also encountering problems unlocking the two free Agents at the start of the game.
We're aware of issues with players not being able to earn rewards from the Battlepass. We have fixed this moving forward for everywhere but APAC. Next we'll move on to getting you back what you should have earned by now.

Valorant Battle Pass Not Unlocking: How to Fix
Riot Games acknowledged and fixed the unlocking problem for all regions except for Asia-Pacific. If you're not in Asia-Pacific, you shouldn't have any problems unlocking things on the battle pass anymore. Just make sure you're on the latest update to get the any new fixes.
Riot Games is still working on retroactively getting players back the things they've missed because of the issue. A solution hasn't been issued yet, but the developer assured that it is actively working on it.
If you were affected, unfortunately you'll just have to wait until Riot Games gets you back the items you missed out on.
The game went into emergency maintenance just hours after launch, addressing issues with connectivity and the store not restoring point acquired in the beta. Most of these issues have been fixed, but the shaky launch of Valorant has set a sour note for many players.
