Invisible in Group Rides

Last evening I joint a group ride event which I have done a few times before but this time I know I was part of the event as I had the jersey and started with everyone else but I could not see the leaders beacon or see any messages and I seemed invisible as the sweep just past me without seeing me. (Normally I hang at the back). I updated Zwift since my last ride so I don’t know if that has anything to do with it or is there some setting I have stuffed up.

Just to add a funny note to my previous post. I won a green jersey on the sprint as it appears I was the only person competing. I know that would never happen if all was normal (but I appreciate it anyway)

Sounds like a network connectivity issue! I’d advise troubleshooting your connection using this guide for next time: https://support.zwift.com/en_us/-check-your-internet-connection-error-running--Hy_P4XfL7
