Update: unfortunately, it’s not possible anymore to connect your YouTube account to hihaho. YouTube doesn’t support this at the moment.
This means that when you put your videos on YouTube and add interactions in hihaho, an overlay with advertisements will pop up when the video pauses.
If you don’t want this overlay to appear, it’s best to upload your videos on another platform. Vimeo is another platform you can use for free.

The good news is: it will soon be possible for everyone to upload your videos directly in hihaho. Then you don’t need to upload them to a platform anymore.
