Browser limitations since new update to animate 2020 v.5

Hi everyone,

since the newer versions of animate 2020 v. 0.1 to animate v.5 I can not click any buttons/clicktags in my html anymore. In the older versions it wasn't a problem ever. I know, that I can test it live on a server or with the preview (strg+enter), also when I set the browser security limitations off. But still it's confusing and laborious when I can not test it offline easily. 

Therefore I wanted to get an older version again. But I can not find one to download in the cloud? Is there any possibility to get an older version like animate CC 2018/19? 

Or a publication setting to get a working html file for offline testing?

Thank you so much in advance!
