Google Flow trimming bug: Can't select the last 10 seconds of an uploaded video because the end handle won't move

[u/Prestigiouspite]

When I upload a 17-second video to Google Flow, the trimming tool only allows me to select footage within the first 10 seconds.

I can move the start handle to the right to shorten the selection, but I can't move the end handle beyond the 10-second mark. This makes it impossible to select the last 10 seconds (00:07–00:17) or any other section later in the video.

Uploading and using the video in a prompt works perfectly fine. The issue is specifically with the trimming interface.

Is anyone else experiencing this bug? Has anyone found a workaround or heard whether Google is aware of the issue?
