For info, in case anyone runs into a similar problem:
After updating to the latest Lineage version a Cordova app on my device wasn’t working anymore and the log showed the following error:
`'file://' has been blocked by CORS policy: No 'Access-Control-Allow-Origin' header is present on the requested resource."`
After some investigation I found the following bug report:
I checked the chromium-webview version on my device: 76.0.3809.89
According to the issue this is the version which has the problem. It should be fixed with version 76.0.3809.111.
