Thank you for your response. The application is not sandboxed, because it would break some of the features. But it is notarised, yes. In the console, I can see messages regarding the verification of the notarisation, there is no issue on that side.

@Claude31 Not yet, but this is what I've planned to do if I'm unable to sort it out with my next attempt (i.e. replacing usages of WebKit)
