I find datadog's UX to be one of the least user friendly and find myself constantly frustrated by how inconsistent it is. Looking at a time span in logs? Click a link to a trace in APM and it's reset.

Looking at process cpu use and there's no time scale...

Some visualizations you can cross filter on, some you can't. Some only hide things in that specific visualization.

It's also very slow.

It also doesn't work at all on mobile.

Not sure why anyone would be jumping to use this.
