I started to try the new support for Custom Tag Sources for Mac. But it always appears the error message: **The resource could not be loaded because the App Transport Security policy requires the use of a secure connection.**
Does anyone have a solution or hint for me?
Best wishes, jcweb

It's probably a tag source that is using HTTP instead of HTTPS — the latter is required to be used by Mp3tag.
Can you point to the respective tag source and maybe even try replacing all occurrences of `http://` by `https://` in the `*.src` file?

That's it. Thanks a lot.
