From version 1.2.1 I'm unable to update the extension to higher versions.
Switching to version 1.3 I get a 500 error on the site, switching to 2.x I get this error:
The class "Websedit\WeCookieConsent\Resource\Rendering\YouTubeRenderer" you are trying to register is not available.
At each update attempt the typo3temp/autoload folder was emptied and all caches cleared.
