I manage to import CSV files into Anki desktop. The cards look ok when I view them in the desktop app. When those apkg files are exported and imported into Android or iPhone apps, we get the following error message:
Please update to the latest Anki version, then import the .colpkg/.apkg file again.
What settings might I be missing?
All apps should be up to date.
Decks created manually in desktop export and import to mobile app fine.
UTF-8 files - still getting the error message.
