I recently did a software update and ever since then I am not receiving text notifications. I have the Galaxy S6 and am using Message+. I can hear the notification when a text comes through, however the blinking light notification is not working. The only way I know I have a text is if I turn the screen on. I have checked all of the settings (LED indicator is on, Message+ app notifications is on, etc.) and everything indicates that I should be receiving the blinking light notifications. Please advise on how to fix this issue.
