I’m not sure if this is more of a GitHub issue or not, but I figured I’d start here to better understand the issue. I just fired up the demo chat app and am working through a fresh Rails 6.1 install to see all the necessary changes.

On page load in Chrome and Safari (but not Firefox [which I’m aware the demo was done in]), there are a series of warnings about link preloading. Is this expected?

So far I haven’t seen any negative effects; more annoying than anything else. But I want to make sure I haven’t done something wrong, and perhaps leave a clue for any future people who are curious.

Same problem started to happen with my app. If I don’t import @hotwired/turbo-rails (I’m using webpacker), the warning disappear.

Hi @jmckible,

did you solve this? Just started to use turbo&stimulus and have same behaviour.

Nope, never got to the bottom of it.
