Hello everyone,
i’ve fixed my old problem ([Solved] Ionic 3.6 - Problem with IonicPage url loading the wrong page) but by fixing that another problem came out.
When i refresh the page or copy and paste the link on a new tab, the page is loaded too fast, my variable are sitll not initialized so i get errors (while if i inspect the code and look at the var, they are ok since after the error the var are filled with the right value).
I think the problem is that IonicPage load before the app.component.ts (since i tryed to move the code of var inizialization before the platform ready and it didn’t work) so it fail to find filled variable…
I can’t even link my online test since online it works correctly, but locally it returns the errors…
Does anyone have the same issue? Have found any solution?
