Dear Weblate Thunderbird Community,

Please note that we are sunsetting this Weblate project. While the original setup was tailored for K-9 Mail only, our expansion to include Thunderbird for Android, Thunderbird for iOS, and other upcoming projects requires a more robust, unified structure that this project can no longer support.

To accommodate this change and manage multiple translation scopes efficiently, we have migrated and reorganized the work into a new unified project: Thunderbird Mobile.

Effective immediately, all translation work must occur in the new project.

We have migrated all previous reviewers and contributors to the new project setup. Should you experience any access issues or problems with your workflow, please contact the maintainers.

Thank you for your continued contribution. We apologize for any interruption this necessary transition may cause.

🔗 Please use these going forward:

• Thunderbird Mobile (Main Project): https://hosted.weblate.org/projects/thunderbird/ • Thunderbird for Android: https://hosted.weblate.org/projects/thunderbird/thunderbird-android/

The translation is temporarily closed for contributions due to maintenance, please come back later.
The translation was automatically locked due to the following alert:

When using Push, <xliff:g id="app_name">%1$s</xliff:g> maintains a connection to the mail server. Android requires displaying an ongoing notification while the app is active in the background. <xliff:g id="optional_extended_explanation">%2$s</xliff:g>
Při používání Push udržuje <xliff:g id="app_name">%1$s</xliff:g> spojení s e-mailovým serverem. Je-li aplikace aktivní na pozadí, Systém Android vyžaduje zobrazení průběžného oznámení. <xliff:g id="optional_extended_explanation">%2$s</xliff:g>
