When I reboot with open browers based on Chromium after reboot, there will be three empty browser windows opened if that browser is running from a deb (in this specially with Chrome and Edge). The content is not restored, I still have to click for the restoration of the tabs. It will be working fine, if the browser is installed as snap (Chromium in this case).
I strongly suspect this is an app issue.
wayland or x11?
