If you subscribe to a Meta One plan, you can add links to a set number of posts and reels each month based on your plan:

• Meta One Advanced plan: up to 4 posts and 4 reels with links per month
• Meta One Expert plan: up to 8 posts and 8 reels with links per month
• Meta One Max plan: up to 12 posts and 12 reels with links per month

Meta is trying to sherlock Linktree. But I can't stop and think it's completely bananas that the internet was built on hypertext and openness, and Instagram created a silo and now it's requiring content creators to pay so their users can have a way out.
