Talked to Verizon store today they called their Verizon techs, said the fix is reset network settings [under backup and reset]. Did it this morning and everything is finally working great.
Thank you so much! I haven't been receiving texts from one person since the update (my husband) unless on WiFi or data and your solution fixed it! I have spent hours trying to correct it. You have no idea how much I appreciate it. Thank you, thank you, thank you!
