Keyboard freezing on comment section
Is this with iOS 26 beta? If so, it's a beta; there are going to be issues with third-party apps because they haven't been written to work with iOS 26 yet.
It's up to the developers of the TikTok app to update it to work with iOS 26. However, even if they update it, they cannot release the update yet as the final version of iOS 26 has not been released yet.
This is one of the things you have to put up with when testing beta software.
You can either wait for iOS 26 to be released in a few months' time, or you can downgrade your iPhone to iOS 18.5 and use TikTok as normal.
