Max number of Jumping Sumo per WiFi channel?


We’ve organizing an event that we will use many Jumping Sumos for a performance. We find that original Jumping Sumo (first version), if 2 Jumping Sumo uses same WiFi channel (e.g. ch36 in 5GHz WiFi), one of them may be disconnected from the app suddenly. However, for Jumping Night (second version), we try to configure 4 Jumping Night using same WiFi channel and none of them will be disconnected.

We would like to know what is maximum number of Jumping Sumo can be shared to use same WiFi channel, for both Jumping Sumo first version and Jumping Night second version respectively?
