That's a bit unfortunate, sorry about that!

I only checked English, French, Dutch and German and assumed that Spanish would be OK. Was this for drag & drop. And do you maybe have the video? Maybe I need to tune the quality threshold specifically for Spanish videos.

I actually did the same video on desktop and the same answers worked fine! Screenshots of it failing in an android webview, but passing on desktop firefox: https://imgur.com/a/vALlFdH.
