There’s a bug with it, introduced last month or so… expect it to take months to be fixed.
To get around it, for now, the only solution I’ve found is to click the tabs in the first couple of seconds of front page loading. If you wait too long, it is unresponsive.
I suspect there’s a JS bug somewhere. It’s not the first time Asustor has broken Surveillance and made it unusable. Last time, it took about 3 months to fix.
When it works, it’s OK. Testing before releasing updates is seemingly non-existent.
Okey dokey, you go first.
