Apple

I was on a free manga page on safari and saw a “would you like to let page name send you notifications?” I clicked “no” automatically without thinking and next thing I know it’s close out of safari, clicked on settings, scrolled somewhere and started to download or type a whole bunch of random stuff in some search bar on settings, it all happened so so fast! Before it could finish I swiped up and got rid of the settings.

Wtf just happened? Should I be concerned? Does anyone know wtf it was trying to do? I’m worried they could be on my phone (idk if that sounds paranoid haha) so I’m avoiding opening up my banking apps.

Thank you for any help!!
