Screensharing eternal loading in ios

I install spreedme app and setup my own nextcloud, and with problems can get a video call, but when screensharing show this:

I have ios 10.3.3 and 2.2.9

How solve it?

Can you explain, why this issue is linked to nextcloud?

From yout description this is a bug for me. Maybe your issue is addressed to the wrong community.

Nop is for own nexcloud with spreedme app installed
