Short answer: because the mobile app doesn’t support purchasing or changing plans yet. Plan upgrades (including Starter) are only available on the website, and your web subscription will sync to the app after purchase. (help.elevenlabs.io)
If you already started a subscription through the Apple App Store or Google Play, that subscription is managed entirely by the app store; to move to a website plan (e.g., Starter), cancel the app‑store subscription, wait for it to expire, then subscribe on elevenlabs.io. You can’t modify or cancel an App Store/Google Play subscription from ElevenLabs. (help.elevenlabs.io)
