Hello,
I have created some screenshots where you can see that Pamac shows different AUR info’s on all my 3 Devices, i also made sure all system has the same Pamac-GTK3 10.7.0-1 version installed, i also tried to switch in the past to another Pamac-gtk (which is gtk4) for a short time, but i reverted back to GTK3 since the issue persist.
(Laptop has the worst Pamac behavior and ONLY shows self installed AUR Packages like EDDIE VPN, but refused to display any AUR Info for outdated Foreign packages):
