With iOS 18.3.1 comes a newer version of sqlite3.
I managed to get some data out of the sms files after exporting data with the latest sqlite3 container and then read it back with the version bundled with mvt.
But I do believe that some data got lost in translation.
If anyone can point me in the direction for building a newer container I could give it a try.
Some sanitychecks about what version of sqlite3 was used to create the files compared to what version of mvt is available would be nice.
