Crash report: Enter key makes newline. How to send input?

i'm trying to send feedback on an app that crashes. I run the app, when it crashes i get a popup asking if i want to report it, which sends me to a Feedback form with:

• email to use


• Write your feedback text field


• Include system logs checkbox

After feedback text is typed Enter key just adds a newline. There's no Send button to click on, so it seems there's no way to proceed...

I've tried different keyboard apps, no luck with google keyboard, swiftkey or even keyboard pro which has a setting to force enter key to validate on some apps.

Using playstore 6.0.5, android 4.2.2
