Lets assume following scenario, I have two sites:example1.comexample2.comWhen user visits 1 there is a prompt please signup to a newsletter. Same thing happens when user visits 2.However when navigating from 1 to 2 I don't want signup form to be shown.My first thought were 3rd-party cookies, but it seems that they are blocked / not working:https://stackoverflow.com/questions/4701922/how-does-facebook-set-cross-domain-cookies-for-iframes-on-canvas-pages?rq=1https://stackoverflow.com/questions/172223/how-do-i-set-cookies-from-outside-domains-inside-iframes-in-safari?rq=1Another thought is to append #noshow for each URL but that would require some work - for instance a script that would intercept click / tap events and modify URL structure depending on the address. (but that seems hacky)I wonder if you know a robust well-established solution to this issue?Thanks
