Uninstalling the app only clears the app-level cache and data. When you log into a new account, the only thing that changes is the session token. All other device identifiers remain unchanged. So if you were only banned on one account, you might still be able to create and use a new one this way. I’d guess your ban was likely content-related.
But if new accounts keep getting banned right after creation, you should consider using a different phone or logging in through an antidetect browser like Multilogin, Hidemyacc, Gologin, or any similar option. This helps ensure you are operating in a completely clean environment. Also, if you're managing multiple accounts, you’ll need more than one proxy. Avoid using rotating proxies. Hope this helps.
