Where to download a working APK
Make sure you opened the current download page and download the file on a stable connection. Use a trusted download channel — it reduces install and login errors.
Installation and first launch
On first launch, grant required permissions so the app runs without limits. After installation, check that the version is updated and the interface opens correctly.
How to fix common issues
If the error persists, remove the old build and perform a clean reinstall. If signatures conflict, fully uninstall the previous app version.
