In general everything goes slow, but certain actions are impossible to perform… for example, if I press the button to add recording, the page keeps loading continuously…
In fwconsole debug, I see some warnings when I the button are clicked
Sorry for disturb… I tried from another computer and it worked fine.
The problem was my PC. I had to clear browser cache, install a pending update of windows 10 … and after restarting my PC everything is going well for me.
