use {{t ...}}, it stops working

changed hard coded "Loading" to use {{t "loading"}}

added {{t "yolo"}} to weather page

now both loading page and weather page stops working.

another discovery is that the bookmark app is also not working,
it is pretty much in the same situation.
a frame is displayed for the app and no content is in it.
