Description

Well I had to migrate a large codebase from some old version of angular to angular 19. Little I did know I was about to open the doors of the hell. I spent 1 f. day to understand how to migrate. "oh you need to just import modules on components that's all" yes, sure. After a while a give up and created a new project, added angular material, disabled ssr, added a simple material slider and ran the application. Always the same f. issue: on desktop everything works perfectly, but when I access the angular app on mobile nothing works. When I go to chrome://inspect it says something like "this configuration requires zone.js". So I import it in the main.ts file but nohting changes. It's so disappointing. I used to love angular but I think I need to change framework at this point. Not even gpt o3 could understand what was wrong jesus
