Entire thread about a lot of people experiencing the same exact issue. All seem to be on Verizon, not sure of your situation.
No acknowledgement from Samsung and no way to resolve this at this time other than to use the Verizon Messages+ app. Seems Samsung pushed this update and basically made all other messaging apps (including their own) unusable besides the Verizon bloatware.
Note that they archived the thread you linked without posting a solution. They're trying to hide it from us too. They'll archive this thread soon bc we are pointing out a fatal flaw in their OS update. Thanks Samsung! Great customer service (not).
Still no resolution or even acknowledgement from Samsung on this.. @SamsungJoJo only tagging you in here because I see you're a Mod in this community. We would really appreciate if this issue was addressed.
Tagging you in here as well since I see you're a Mod that's commented on recent posts on this community. Can this issue please be addressed? There are multiple threads about this same issue throughout the community and no one is addressing it. In fact, some threads have even been archived with no resolution.
Please help, this issue has caused all MMS messaging to become basically useless since the update was pushed.
