Apple's SMS obstacle

Last year, I changed my Apple mobile phone and imported thousands of short messages from previous years into Iphone 12. All the short messages were out of order, and the time became the import date, so the new short messages I received could display the date normally. Later, it was found that after clicking the imported SMS, the information was directly changed to the date of viewing and changed to the top. Click to open one and change another. After restarting the mobile phone, all SMS dates will become restart dates, and the above process will be repeated. Delete all messages and import them again. Restore factory settings.

To be honest, I can understand that the system is different and the display mode is different. After all, it was the text messages saved by several different mobile phones before. You can have an import time, I can accept it. The key is that you don't change the time at one o'clock. When you restart, everything will change the time. I can't make do with it.
