I've found some Issues and so asking for a refund.

Issues:
1. The smartphone webinar view with the speaker image detached from the slides is not good UX, it's what makes me want a refund - I can imagine the drop rate rising and prefer to use other platform just because of this.

2. I've documented that your translation is not working correctly, when a attendee joins he gets it in English, although it's configured for another language. The same happens inside the webinar with the buttons to change views and also on the landing page. I can send proof.

3. Another glitch is that you can scroll the presenter's video to under the slides if on a smartphone (it happens easily). Have documented that as well.

On a positive note, I'll say that the 12 fps are usable - guys just test this like Olman suggested - I did and recorded and it was ok to watch.

I'm giving this 3 stars because the platform itself is well built and it seems that they will be a good competitor to Zoom when they get it right, but for me to risk having people droping from a webinar due to poor UX is not an option since my customer acquisition cost rises as a result.
