Anyone here warming TikTok accounts using cloud phones?

Quick question for people managing multiple TikTok accounts. I’m setting up a batch of new accounts and testing different “warming” approaches before posting consistently. I’ve seen people mention using tools like Geelark for managing sessions / environments.

Does it actually make a difference for account health and reach? Or is manual warming still better?

Trying to avoid instant shadow issues since I’m running multiple accounts in parallel.

Would appreciate any real experiences (good or bad).
