Problem
So I got my phone showing up as a device in Remote Devices in Chrome Developer tools.
but
- the version of Chrome is missing
- the list of tabs in Chrome is missing which means
- the inspect button is missing
More Information
- I have adb server running on my laptop where I'm running the DevTools.
- When my co-worker hooked up his phone to my laptop, keeping everything else the same, there was no issue as described above. Worked normally.

There can be many things which could go wrong. Just check this things, Maybe can help you -
