Text messages missing
Missing one months of text messages after transfer from wife’s old iPhone 7 to her new iPhone 14 pro. Any solutions would be appreciated
Sounds like the backup of your wife's "old" phone was likely about a month old. That would explain the loss of data for the last 30 days or so, since when you transfer data from a backup of an "old" phone to a "new" phone, the "new" phone will look just like the "old" phone did at the time of the backup.
Now, if you are saying that you backed up your wife's "old" phone just before you set up the "new" phone, then there are more pieces of the puzzle missing at this point.
