Symptom
Apps without digital QNAP signatures have an exclamation mark next to their icon. This can generally be resolved by updating the app to its latest version.
Solution
There are two ways to solve this issue: Update the app to the latest version (recommended) or allowing the installation of applications without a valid digital signature.
Update the app to the latest version
- Re-download the app.
- Apps developed by QNAP should be downloaded from the QNAP App Center website.
- Apps developed by third-parties may not be available from the QNAP App Center and may be available from the Qnapclub Store.
- Reinstall the app manually. For more information, see How to install QNAP applications (.qpkg files) manually?
