Hey @lucasbento! Sadly, I have no updates. I might try to take a look at the code and try to solve it myself but I have no experience with iOS native code. If I have any kind of success I’ll create a PR and let you know!

I’m experiencing the same behaviour when sharing using whatsapp. When sharing with email the file is attached but with no extension.
