Looking for help when dev an app extensions ui live preview( No HMR?)

[every-tuesday]

I'm working on making a post-checkout-ui extension and running into an annoying work flow while developing. When trying to make the layout and design, every time I make change and need to save and test, I have to re-enter all the information and go through the whole checkout process each time to see the changes and test them. I was hoping for HMR or something that would speed up development of the layout but this is killing me. Wondering if anyone has any solutions for maybe developing a static ui on another page or something. Any help would be great!

Thanks,

S

Looks like I just had to restart the app server and extension server and everything is working properly.
