No Updates in More Than a YEAR!

[Sticks]

Too bad, sorry to hear that you had this experience.

I can only speak for myself, so my experience with JK and their support doesn't mean it will be the same for each user.
In all honesty, I had problems and issues at the beginning too.
But since a year or so I really don't have any issues anymore.
Once in a while I'm unable to join a session - log out- log in- and voila, it works just fine.
The loud crackling, yes, I remember that. I didn't hear that in a long time.
Usually it is caused by an improper setup on one session participants side. We had this many times with one specific musician.
As soon as he joined the session with video there was a very strong crackling and distortion in the audio.
Everybody could hear it, sure enough the blame was put on JK.
When said musician turned off his video the crackling was gone too.
I think it is safe to say that many issues with JK are solely caused by the users/incorrect setup.
We still play together on a regular basis, but no video.
The sound is good and we have fun.

Have a great week - keep jamming!
