Montana's TikTok ban faces legal challenges from creators.

Montana has become the first US state to ban TikTok on all devices, even personal ones, but legal and technology experts say there are huge hurdles for Montana, or any state, to enforce such a law. The TikTok ban immediately prompted one lawsuit from TikTok users who allege it violates their First Amendment rights, with more legal challenges expected. Even if the law is allowed to stand, the practicalities of the internet may make it impossible to keep TikTok out of the hands of users.
