I use kaptu with raspberry pie and chromium. I make html and start from command line
“chromium-browser script.html” If chromium is open everything is ok. If i reboot rpie html page is opened and after some time i get window with error “panel tab id recorded expired!” So kaptu can`t start script automaticaly. But after close window i can start script by manual
We don’t support Chromium officially yet, so we never test on it. But we plan to support it in the feature. You may want to try the V5.0, maybe we fixed this issue accidentally ,)
