I have tried to get this answered many times but it never seems to help. When I send from my Samsung 9+ to groups of iphones users my texts periodically get stuck sending. I then have to clear all data from the app and turn my phone on and off. It then sometimes works and I lose all of the texts that were stuck sending. It is very frustrating as it now happens multiple times a day. Below are some of my answers to other chains that i responded to people but never was followed up.
This is not an app problem. I have tried on multiple apps and the same thing happens. It has been happening for over a year. It happens periodically when i send from my Samsung S9+ to a group of iphone users. It happens on multiple chains and only in that situations. It does not happen when one on one so only when I am sending mms to iphones. I have uninstalled, force stopped, cleared data, turned on and off phone, replaced phone and anything else i have read other places. This is a verizon issue. If there is anyone who could figure this out I would be forever indebted. I also am a 20 year verizon person who is considering leaving.
Also just to be clear this has nothing to do with wifi. it is the same if i am on wifi or data. It just says "sending" and no one sees it. It also is on the original verizon app that came with the phone.
