I have an older Samsung S8 with Android 9 on it if that makes any difference. It does something I find really annoying. I might not look at my phone for an hour, but then when I pick it up, usually because I want to immediately do something like send a text, it will go crazy for a few minutes while it catches up with every text and IM message from other apps that have happened during that time. I don't want this. I want it to notify me as the messages come and not save them to overwhelm me later. Most of the time, I am already aware of the messages anyway as I get them on my computer. I have looked in the settings, but I can't seem to nail down what setting would control this. Any help is greatly appreciated.
