What phone do you have? pixel 3a
What plan are you on? 1g data
Does your plan include data, or just talk & text?
Within the last week some messages will list as being sent from the text q, but the contact does not receive them, or receives them a day or two late. I have tried to delete and re-enter the contact information, but that does not fix the problem. I had the recipient do the same, still no dice.
Some online help forum said try the republic anywhere app, however some of those people said they had similar problems. Those were different phone models though.
