+<div class="warning">
+
+There is currently a problem on Arch Linux and Arch-based users specifically that's preventing Flatpak from automatically pulling NVIDIA Flatpak drivers utilizing the frozen 580xx driver branch due to the drivers being advanced to the next patch without any Flatpak equivalent drivers.
+
+This is caused by Flathub having [issues with their GPG keys that's preventing builds from being signed and published](https://status.flathub.org/).
+
+If you haven't upgraded, **it is recommended to deter upgrading until then or otherwise exclude the 580xx drivers from upgrading in your pacman config or AUR helper**.
