Loading the script 'chrome-extension://hkledmpjpaehamkiehglnbelcpdflcab/video-data-sync-ui.js' violates the following Content Security Policy directive: "script-src 'report-sample' 'nonce-rGONgLkVoL96Az4Uq0rvIw' 'unsafe-inline' 'strict-dynamic' https: http: 'unsafe-eval'". Note that 'script-src-elem' was not explicitly set, so 'script-src' is used as a fallback. The policy is report-only, so the violation has been logged but no further action has been taken.

@KileOR Just gonna copy and paste what I said on #848

this is related to #845 and #821. To fix the issue, head to chrome://flags/ and disable experimental web platform features. This should resolve this issue. Unfortunately, this won't allow one to select from multiple audio tracks when playing local media. If you do want to be able to select from multiple audio tracks, you can find multiple disable CSP extensions on the Chrome Store; however, keep in mind that CSP is a security protocol. I do know that the maintainer was working on this PR #811, so it would probably be best to wait for a future update.

@NovaKing001 Disabling experimental web platform features works. Thanks!

@killergerbah It feels strange that I have to disable Experimental Web Platform Features just to use a single extension.
If possible, could this be fixed on the extension side instead?
