Hi @MoosterJ
Welcome to the Sonos Community!
I think the reason you’re unable to add a product from your phone probably has a lot more to do with your network than with your phone.
Hopefully, you’ve got your new product setup now anyway, but if the same happens again in the future, please try the following:
Try turning your WiFi router off for at least 30 seconds, then turn it back on. Wait for WiFi to return before opening the Sonos app, and try again. If you have a WiFi booster or extender that your phone might be connecting to that your iPad was not, I recommend turning it off - at least until your new product is added. These kinds of devices are not supported.
If it still fails to add, I recommend you get in touch with our technical support team, who have tools at their disposal that will allow them to give you advice specific to your Sonos system and what it reports.
I hope this helps.
