No more calls / Video calls from Caprine

[Philboo]

Hello,
Since recently it is no more possible to have audio calls or video calls within Caprine (the message "your navigator doesn't allow calls" appears when you go with the mouse on the phone icon).
What can I do to update my navigator ?
Thanks

Philippe
