After complaining, they quickly got to work. Support was a bit slow at first, but now it's back, and I think they've fixed the problem with displaying the WooCommerce page. Hopefully, I can now display WooCommerce products with a pop-up!

I also found that showing the popup in specific countries didn't work. I hope they'll test this very soon. When I use Audience, Geolocations, or Browser Locations and test with a VPN and clear the history, the popup immediately stops working. Please check this with Support.
Thank you.
