The same question was posted over two years ago by @lukelim91 here: Connecting more than one mobile device to APC Wifi
In that thread @HunterC said:
“Hi, currently it cannot, but it is a feature we are planning on implementing this feature shortly.”
Again that was two years ago. For some reason it went back and forth and finally @AlyssaWOAHAnova closed the topic saying the question was answered even though it wasn’t.
I have been waiting for this feature since I got my Anova, it’s really kinda dumb that my wife and I both can’t use the same machine without disconnecting the other. Not sure what @HunterC meant by “shortly” but I would think that is less then 2 years. Not even sure if its still on their roadmap and haven’t seen any other updates.
