zoom stream to facebook fails after connected to testgroup

hi there,

i need help because i give a workshop tomorrow.

i have been doing this already but this time it does not work. i created a test group on facebook. opened zoom to stream to facebook and there were some settings that asked me to which group. i only put "test group". if i now want to stream to the real group i cant - it does not appear. any idea how to activate that again?? 

any hint is helpful!!

cheers katrin
