Thanks for responding.
But as rand said, I also get tee “blank screen” - not totally black, but no splash screen showing IP address of the Pi like few months ago. I tried to update and upgrade in the 32-bit version (Debian 10, buster) but still can not see anything in “/etc/systemd/system/screenly-host-agent.service”
I managed to bring it on if I use the pre-built image from here: Releases · Screenly/Anthias · GitHub
(But after imaging, people should plug in the Internet and turn on the Pi and wait for 10-20 mins for it to be automatically loaded)
I’n trying with latest 64-bit image, hope that it has the “screenly-host-agent.service” file
