Yep, unfortunately these are years-old bugs with Meetups that Zwift clearly have no intention or ability to fix. I can only assume that the code is too risky to touch due to how it is wrapped up with other stuff, or they simply have no understanding of it because the original developer of that piece isn’t there any more.
Our only hope appears for them to be to write new code for this clubs, which I assume is why it’s taking so long for this to appear for clubs despite being supposedly in progress for quite some time.
