Error message accessing survey backend after update to 5.8

I have just updated to latest version of Community Surveys and now when I try to access survey in Administrator area I get the following error:

Call to undefined method Joomla\CMS\Document\HtmlDocument::getWebAssetManager()

I tried it on a dev site and same problem. 

I have updated JCE just in case it was that as was suggested elsewhere. 

Any idea how to fix access?


Kind regards
