Failure to reconnect Sonos:3, Connect Amp, ZP100 and soundbar

My system worked until the sonos app was upgraded. (Orange to black icon)  An Ikea book shelf and ZP100 were upgraded and continue to work, but 5 products have become disconnected. Yes I've tried rebooting. Resetting, direct network connections and dhcp address allocations and downgrading (but downgrading capability has been removed) I have a bunch of sonos products with green flashing light that are  available to "connect" but can't register in the system.

Any suggestion or do I throw them away?
