Known issues

Language based date time format in WhatsApp exports

NOTE: This can be avoided by using the WhatApp DB import.

WhatsApp exports have language based time format in export file and for Android without seconds. In my case 01/12/2023, 23:59
The new WhatsApp macOS App has a more usable format [01.12.23, 23:59:42] for the same message as Android, but in my case only loads the last 3 years of chat history.

Please open an issue with a small anonymized sample export and your device language. Or better open a PR with a fix. :)

Missing messages form WhatsApp exports

NOTE: This can be avoided by using the WhatApp DB import.

If a message was part of a sent image the message won't be in the export. I opened an issue with WhatsApp, but don't know if this will ever be fixed.
