It seems something has updated and neither me nor one of my friends can share screen anymore. Clicking on button has no visible result, and in the logs:

We both use "internal" desktop app on Arch Linux, and I tried switching to "Developer > Internal" and "Developer > Production", but both strangely show the same version of webapp:
Wire for Web Version 2018.03.06.2034
Arch Linux
Screen sharing starts
No visible indication, error in the logs.
I couldn't test at the moment in more details, if you can't reproduce I will be able to make some more experiments in the evening.
Thanks for the report. We broken by #2641 that was part of our latest staging bump. Fixed by #2716.
