Yes, if you use layout type as model pop-up then it will act as a blocking pop-up and everything behind this pop-up cannot be changed. If you don’t want this to be blocking pop-up then use layout type as pop-up instead of model pop-up. This might solve your issue.

I’ve had the same issue. However, I wanted the pop-up to be a modal pop-up in order to have a darker background around it. And I found out you don’t necessarily need to switch your layout type to a normal pop-up. Having it set on modal pop-up will work. Also your feedback widget (snippetcall) only needs to be placed on your responsive layout types you use (e.g. Atlas_Default). Important here is to place the feedback widget (snippetcall) in the ‘content region’ of your scroll container rather than in the ‘top region’. So place it just above the ‘Main’ placeholder:
This solution has resolved the issue for me. Hope it helps!
