I can see the pop-up on your website. It appeared after ~5 seconds. The thing is that when you close the pop-up once then it won't appear again. You'd need to clear your browser cookies or try in incognito mode.
Hi! I'm having the same problem - I have previously set up my mailchimp popup with shopsync on the Debut theme and it was working fine.
But after I switched to the Prestige theme, the pop-up stopped showing up. I have checked and the code is still inserted in my theme.liquid file.
I have cleared cookies and tried other browsers but it still doesn't show for me.
Would really appreciate some advice! My site is www.flowwe.sg
I can see that the popup appears on your website:
It's puzzling why clearing cookies or checking in different browser didn't help. I can only guess that maybe Mailchimp tracks closed popups based on your IP address. If that's true then you could try with different Internet connection, for example, on your mobile.
