XS Max updated to latest. About half the time on wi-fi at home if I try to send a non-imessage text (green)it will come up and say it has failed and then I can try to re-send. It is completely hit or miss if these texts go out. I have tried: reset network settings set up phone as new tried linksys router tried netgear router Apple of course blames the router and verizon, verizon blames apple and or the router. You see how it is going. If I take the phone off wi-fi of course there are no problems. Hoping someone can suggest something?
