There is an issue with apps scripts/requests, It throws an error on browser console related to security CSP reports, Here is an example error:
[Report Only] Refused to connect to 'https://XXX' because it violates the following Content Security Policy directive: "connect-src 'self' .shopifycloud.com .shopifysvc.com .amazon.com .paypal.com *.facebook.com sessions.bugsnag.com analytics.tiktok.com bat.bing.com www.google-analytics.com ct.pinterest.com stats.g.doubleclick.net".
So it seems external scripts are allowed from certain domains only.
The error shows
[Report Only] which means the error is informational and shouldn't affect how the script loads. Can you confirm in the network console that the script is indeed being blocked? If this is the case please provide a shop_id or page URL and we can investigate further.
