Issue joining Meetups

Hi - last week I tried to join a Meetup about 5mins late - Zwift said it was allowing me to join but didn’t bring me to the other riders - instead my avatar was hovering in the sky looking down on Watopia! I ended the ride and tried to join again - this time Zwift left my avatar out in the sea with my bike submerged!
I eventually got to the others by searching for them then choosing to ride with one of them - Zwift then positioned me into the Meetup properly!!

Exactly the same thing happened with a friend this morning - tried to join Meetup late and had same issue but was able to join after choosing to ride with another rider.

I use Apple TV and my friend was using a PC (Windows 10) - both of us were running the latest versions of Zwift.
