Samsung S9 T-Mobile Every time I send a message this pop-up appears. I've toggled the read receipt setting on and off several times. Rebooted phone. Cleared messaging cache. Said yes to pop up message, then toggled read receipt off. Only thing I haven't done is clear data which I can do after backing up messages but was hoping there was a fix for this annoying problem without me having to wipe the app. A Google search for this issue has turned up nothing except for one hit for an iPhone in 2017.
