Please update Jami snap for RPI4? it's still "Together"(20201027)

Could you try to run the daemon jamid e.g. with terminal command /usr/libexec/jamid -c -h or similar? Does it fail? Does it succeed? I assume you have no camera on your Raspberry Pi?

Please read Jami not running on Raspberry Pi 4? Jami not running on a machine without camera? and respond there, if you have time. Thank you!
