lost iMessage conversation
The iMessage thread from me to me (I send reminder messages and whatnot to myself here is missing). All data prior to 8/28/2022 is missing. Every other message thread is intact. I did not do anything in particular to cause this, the messages simply aren't there anymore. I was traveling in Europe at the time and wonder if how my phone was configured caused this problem but, as I stated, the only conversation thread missing is that one. Anyone have any tips? The phone automatically backups up so the most recent back up is yesterday night 9/5/22. I would really like to recover this data. Any help is greatly appreciated. Thank you
