ha works fine on a Chrome browser on the tablet

The card works fine on a Chrome browser on the tablet, as well as various browsers on other laptops and phones

When debugging the network requests in the app there are a load of javascript errors and same site origin errors. When I check the same network requests but using the browser on the tablet everything seems to load fine. I would have expected the app to use the same browser engine as the actual browser (Chrome in this case). Is there a reason that the network requests would fail, and some of the javascript would fail to parse/run on the app, but runs fine on the browser on the same device?
