I had this issue recently on my iPhone and got round it by turning off the “auto-join” option for my home network.
Settings>WiFi> Click on your home network name
Turn off “Auto-Join”
Then I performed the connection to the Anova, I “assume” the phone is rejoining the home network before it has the chance to establish the connection with the Anova to perform the setup
Once through the Anova set up process I turned the “Auto Join” option for my home network and everything was all fine from then on.
Give that a go
