I've fixed the following:

mobile-2g
navigation-timing-alerts
navigation-timing-by-continent
navigation-timing-by-country
navigation-timing-by-platform
niedzielski-sandbox-mobile-2g

And the following dashboards looks broken (they have graphs that doesn't work). Ping @Jdlrobson - I can fix them as long as they are in use, do you know?

mobile-web-performance
reading-platform
reading-web
reading-usertype
reading-overview
reading-site-speed
reading-draft2
reading-draft

What about that we start with adding who is responsible for a dashboard (instead of looking at the history?)?

There's one left to fix:

https

One thing: the navigation-timing-alerts had an broken alert: I've changed the graph before to use navtiming2 but the actual alert still referenced to navtiming. The only way to see that was to check the actual JSON. I deleted the alert, saved and recreated it.

Thank you!

reading-platform

Ping @Jhernandez for this one.

Not in use.

reading-usertype

Not in use.

reading-overview

reading-site-speed

reading-draft2

reading-draft

Not in use.

@Jdlrobson is it ok then if I just delete those dashboards that aren't in use?

I think so but don't delete reading-platform without @Jhernandez saying so. I'd also recommend checking with @dr0ptp4kt

@JKatzWMF adding you in here. I believe reading-platform may have been your dashboard based on [T102036#1524744]. Okay to delete?

@dr0ptp4kt Yes reading-platform was mine (As were reading-usertype, and reading-overview). Fine with me to delete.

Thanks all!
