With 7.1 "Share WiFi Settings" no longer works for A3 Pioneer Speaker setup

I am nolonger able to link my Pioneer A3 Speaker with my WiFi network by plugging it into my iPhone or iPad, no message asking "Share the WiFi Settings". I have used various cables, re-booted WiFi and devices etc so conclude either my A3 has suddenly broken, or the 7.1 updates messed things up.

Section E in this PDF is the instructions I have been following https://www3.pioneer.co.jp/support/manual/wss/sma1_3_4/pdf/ARH7143C.pdf

Anyone else with this sort of issue ????
