But when i press on the "Solutions" button it is just flashing for a second. Why is it?

Answer 1

I just investigated a similar issue (which only happens in mobile or mobile mode in dev tools). after removing styles from my tailwindcss.css file I finally arrived at
button,
[role="button"] {
cursor: pointer;
}
removing this solved this blink for me
