Hello community, I am having the following problem with the remix app: When I use the loader action in each router, the problem is that the switch between each router is very slow or when I click on the router, the URL only changes but the view does not change. Has anyone had a problem like this or can help me solve it?

Hello @Louis96 ,

For my case I am using ngrok instead of cloud. But i haven’t phase any problem when i switching the route, Infact theme app extension front reflect the code change take some time, so what can I do to see the changes come quickly, I removed the app save and again add the app.

I am experiencing the same issue with slow route changes; nested routing in Remix seems to be very slow. Is there any way to improve this?
