[Kindle] Error when sending ebooks via email

[brumasribera]

Hey everyone!

I hope you're all doing well. I've been running into some issues when trying to send e-books to my Kindle using the Share by Email feature. It used to work perfectly a few months ago, but lately, it’s been giving me some trouble.

Whenever I click send, the app freezes for over a minute and then gives an error about wrong user credentials. I’ve tried using Outlook, GMX, and Gmail, but the problem persists.

I’m currently using the latest version, 7.15.0 on Windows 11. Here’s a bit more detail from the error log for reference:

Thank you so much for all your hard work and any help you can provide!

Cheers,
Bru
