This is not a problem specific to SportsNow. 


Zoom has introduced that by default each meeting is protected with an identification code. In order to open the meeting directly, i.e. without entering an identification code, the invitation link of the meeting must be used. The invitation link can be found in the meeting information on Zoom and has the following format: https://us04web.zoom.us/j/<Meeting-ID>?pwd=QjVUY21ja0FXRStYZ3ZOZlptSksJQT09

It's best to check the link on another device or where you are not logged into your own Zoom account and make sure you can join the meeting directly. Now make sure that the invitation link mentioned above is used for the livestream in the c settings on SportsNow.
