I can't get the rare purple Valkyrie skin.

That’s really annoying, especially after you collected all the event points. Sometimes Steam accounts have a delay when rewards sync with Apex. Try restarting the game, logging out of Steam, or checking the Event and Special Offers tabs again—sometimes the claim button appears later than expected.

If it still doesn’t show up, your best option is to contact EA support. They can check your account and manually fix missing rewards.

That sounds frustrating! Sometimes the special event rewards, like the purple Valkyrie skin, take a little while to sync between the event tracker and your Steam account. Try restarting the game or checking your inventory after relaunching if it still doesn’t show up, contact EA Support with a screenshot of your completed points. 
And by the way, love seeing the dedication here — the patience needed for perfect prints reminds me of crafting thoughtful Birthday wishes for friends - both take care, timing, and attention to detail!

That sounds frustrating! Have you tried restarting the game or checking if there’s a delay in rewards for Steam users? Sometimes, event skins take a bit to show up. Hope it gets resolved soon! Also, whenever I hit roadblocks like this, I take a moment to read suraheyaseen.com —it’s a great way to reset and refocus. Hope you get your Valkyrie skin soon!
