cannot claim my linkedn premuim

I'm trying to redeem the "3 free months of LinkedIn Premium Career" partner benefit from my Adobe Benefits page (Partner perks), but I keep getting an error from LinkedIn: "You are not eligible for this promotion. This promotion is limited to eligible LinkedIn users and is available only in select regions."

Details:
- My plan is Adobe Express Premium (received via Airtel), member since 2026.
- I'm in India, and a friend with the same Airtel Adobe Express Premium plan redeemed the same offer successfully on the same network, so the offer is available in my region.
- I have never had LinkedIn Premium or any LinkedIn Premium free trial before, so I should pass LinkedIn's "new user" requirement.
- I clicked the LinkedIn benefit link from my own Adobe Benefits page, not a shared link.
- A brand-new LinkedIn account with no history also gets the same error, which makes me think the coupon tied to my Adobe account may already be consumed or flagged.

Could you please check the status of the LinkedIn Premium coupon on my Adobe account and reissue it if it's been used or invalidated? Happy to provide my Adobe account email and any other details you need. Thank you.
