Using a galaxy s9 and in group chats with iphone users after a while my messages will not send and their messages will not come through to me. They show as "download" instead but nothing happens. This has been happening for a year. I switched back to an old iphone 6 and had no issues. Factory reset, cleared cache, etc. on my galaxy and tried to switch back...issues started again within 1 hour. Ridiculous. I just paid this phone off and now I can't even use it because it won't function properly. Went to Verizon store and was told I just needed to upgrade because they couldn't resolve the issue...as if I want to spend another $700 on a phone that will just fail to properly operate
