i've complaint on other post before but the likelihood on why the button is keeping loading there is because it can only be click after all the popups ends popping on bottom right,
that's obvious whenever i closed the apps & open it again, it takes few secs to finally be able to click the blue button.
this error/bug also happens after playstyles got introduced..playstyle introduce>more popup on bottom right.
i know this because i have slightly old version and the watching ads over there is quite smooth compare to latest version
