iPhone键盘输入首字母”没反应“，删除一个字连带删除两个字（The first letter doesn’t register when typing on the iPhone keyboard, and deleting one character sometimes deletes two characters.）

最近好像是升级完IOS27之后？或者之前，反正是最近一段时间经常遇到使用苹果自带九宫格中文键盘，比如输入xiong的时候，x没有，只有iong；还有就是比如我输入“我正好需”，这个时候我删除这个需的时候，好也会连带删除，就是剩下”我正“，看一下这个是什么问题，怎么修复一下，好像也不止我一个人遇到这个问题

It seems like this started after updating to iOS 27—or maybe even before that. Anyway, for quite some time recently, I’ve frequently been running into issues when using Apple’s built-in Chinese 9-key (T9-style) keyboard. For example, when I type “xiong,” the “x” sometimes doesn’t register, and I’m left with only “iong.” Another example is when I type “我正好需” and then delete the “需,” the “好” gets deleted along with it, leaving me with “我正.” Could you look into what might be causing this and how to fix it? It seems like I’m not the only person experiencing this issue.
