hello Torueho83
Welcome to the community.
The Perplexity Pro offer was a “one-time only” offer. Once you used the promotion, it will run out after 12 months. You’ll have to sign a plan with Perplexity if you want to use it.
There’s another promotion on Sunrise Rewards. That promotion can’t be used if you signed up for a similar promotion before. In order to use the new promotion you’ll have to use a different account.
