Hi @Tim_Brennan Just getting back to you on this issue you’re experiencing. I really cannot tell for sure beyond what I’ve written because I do not have any device with a Samsung Internet Browser.
It’s also difficult to tell what your code there is doing - it’s 2500 lines of custom JavaScript for the product configuration alone - anywhere in there could be potential for something that isn’t supported by the Chromium version used in Samsung Internet Browser. And not even saying it has to be that. Could be something else too.
As is, I can’t replicate the issue so unless someone else can pick up from here who has access to said browser and is willing to look in to it, there’s little I can do
