Tiktok reinstalled by itself

Hello Quest1on,

Thanks for reaching out to Apple Support Communities. We've reviewed your question and it looks like you have an app that keeps installing itself. It's understandable that you'd want this resolved, so allow us to assist with that. IN order to better understand why this may be happening, please answer the following questions:

• Has your iPhone been restarted recently?
• Was the TikTok app deleted for sure or just archived?
• Is your iPhone managed by another person or group, like a school or employer?
• Do you use any other Apple devices that share the same Apple ID, and if so, is the app on that other device?
• Is your iPhone updated to the most recent iOS version?

Please let us know this answer. We're here for you. Have a fantastic day!
