Who I have the same questioned this topic

Hello,

For the past week my Unlocked Samsung Galaxy S8+ (SM-G955U1) running Android 8.0.0 with September 1, 2018 security updates and Baseband G955U1UES5CRI1 has been displaying the message "Syncing messages Temporary background processing" in the notification tray and the only way to remove it is by rebooting and after that it will happen again. It will happen if I have good or poor signal and even on WiFi. There was an update to my phone on the 27th I was hoping that would resolve it which it didn't and last night there was an update to Message+ (Version 6.7.1) that didn't resolve it either.
