Joining group rides

Am suddenly unable to join started group rides on my iPad. Can see others joining by mine keeps saying that it is looking for riders. It used to then join them but now does not

It happened to me also yesterday. Today I started 2 races in the wrong world.

Were they #worldswap races?

After restarting your Zwift app are you able to try joining those group rides? Is this still happening to you Joan? N
