Interactive Video

I have an interactive video on my site with one button to press at the end of the video that takes you to an external URL. I have recently found that by having your plugin activated on my site it slows down the site by 4+ seconds, which is crazy. What can I do to fix this? Or will I just have to not use your plugin?

I use H5P on WordPress.

I have the latest version of the plugin, and the latest version of the H5P Interactive Video Library.

When I want to add a bookmark, whether on an integrated video or on a YouTube video, it does not work, no bookmark is added.

I notice this is due to a JavaScript error and I have attached a screen copy.

I also noticed the library version is 1.19.3, but on another WordPress H5P install:

Hello,

I have been trying to add a captions file to the an Interactive video, and everything appears to be just fine, but the captions are not showing when I play the video. I have validated the vtt file and it checks out alright.  I am using H5P on Wordpress. This is my first try at doing captioning on a video so perhaps I am just missing something simple.

Thanks for any help anyone can give!
