Gatsby: A preload <link> was found, but not used.

Hello Mates,

Lately our score went from 95 to 40-50 on Pagespeed, and it's because of the warnings shown below;

I"m not sure if it's a plugin conflict, or it has something to do with the gatsby-plugin-preload-link-crossorigin.... Here's my gatsby-config file:

What are you thoughts guys? please illuminate me.

Cheers.

What version of gatsby are you running? I would remove gatsby-plugin-preload-link-crossorigin unless you know what you're doing.

[Polyhistor]

Well, I'm using version 2... and I've picked gatsby-plugin-preload-link-crossorigin as a solution to Page Speed warning about cross-origin..... So let's say if I get rid of the plugin, how can I dynamically handle the cross-origin for preload links?

[Polyhistor]

@wardpeet Hey brother, any news on this matter? I could not find anything in the documentation...

[ankesh7]

Same issue with font and stylesheet preloading

[wardpeet]

i'll be checking it out today, sorry for the delay.

[Polyhistor]

Any luck or solution?

[ashleynexvelsolutions]

Any word on this? I seem to be running into the same issue. @Polyhistor @wardpeet

[darokrk]

Same problem here.

Did anyone find a solution?

[panzacoder]

Bumping again, this appears to be tanking my lighthouse scores.

[gabrielacueva]

Same case here, any news?

[gabrielgiordan]

Same here, any workaround? These Lighthouse complaints are rather annoying.

It has something to do with how the gatsby-plugin-offline preloads these assets.

[cmaycumber]

I'm running into the same issue. I'm just curious if this error is actually impacting lighthouse performance or whether it's harmless because we've noticed a significant drop across the board for one of our Gatsby sites performance-wise.

[edbzn]

Also impacted, can we reopen this?

[conspireagency]

Would like to see reopened as well. Not using "gatsby-plugin-preload-link-crossorigin"

[paultannenbaum]

Also seeing this from our lighthouse scores when attempting to use the gatsby-plugin-offline. At least some communication from the gatsby team on if this is something they are going to look into would be appreciated.

Most likely a duplicate of #25360
